FEATURES

DESCRIPTION

The LMV358-N/LMV324-N are low voltage (2.7V to

5.5V) versions of the dual and quad commodity op

amps LM358/LM324 (5V to 30V). The LMV321-N is

the single channel version. The LMV321-N/LMV358-

N/LMV324-N are the most cost effective solutions for

applications where low voltage operation, space

efficiency, and low price are important. They offer

specifications that meet or exceed the familiar

LM358/LM324. The LMV321-N/LMV358-N/LMV324-N

have rail-to-rail output swing capability and the input

common-mode voltage range includes ground. They

all exhibit excellent speed to power ratio, achieving 1

MHz of bandwidth and 1 V/µs slew rate with low

supply current.

APPLICATION INFORMATION

BENEFITS OF THE LMV321-N/LMV358-N/LMV324-N

Size

The small footprints of the LMV321-N/LMV358-N/LMV324-N packages save space on printed circuit boards, and

enable the design of smaller electronic products, such as cellular phones, pagers, or other portable systems. The

low profile of the LMV321-N/LMV358-N/LMV324-N make them possible to use in PCMCIA type III cards.

Signal Integrity

Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier

package, the LMV321-N/LMV358-N/LMV324-N can be placed closer to the signal source, reducing noise pickup

and increasing signal integrity.

Simplified Board Layout

These products help you to avoid using long PC traces in your PC board layout. This means that no additional

components, such as capacitors and resistors, are needed to filter out the unwanted signals due to the

interference between the long PC traces.

Low Supply Current

These devices will help you to maximize battery life. They are ideal for battery powered systems.

Low Supply Voltage

Texas Instruments provides guaranteed performance at 2.7V and 5V. These guarantees ensure operation

throughout the battery lifetime.

Rail-to-Rail Output

Rail-to-rail output swing provides maximum possible dynamic range at the output. This is particularly important

when operating on low supply voltages.

Input Includes Ground

Allows direct sensing near GND in single supply operation.

Protection should be provided to prevent the input voltages from going negative more than −0.3V (at 25°C). An

input clamp diode with a resistor to the IC input terminal can be used.

Ease of Use and Crossover Distortion

The LMV321-N/LMV358-N/LMV324-N offer specifications similar to the familiar LM324-N. In addition, the new

LMV321-N/LMV358-N/LMV324-N effectively eliminate the output crossover distortion. The scope photos in

Figure 49 and Figure 50 compare the output swing of the LMV324-N and the LM324-N in a voltage follower

configuration, with V_S= ± 2.5V and R_L(= 2 kΩ) connected to GND. It is apparent that the crossover distortion

has been eliminated in the new LMV324-N.

CAPACITIVE LOAD TOLERANCE

The LMV321-N/LMV358-N/LMV324-N can directly drive 200 pF in unity-gain without oscillation. The unity-gain

follower is the most sensitive configuration to capacitive loading. Direct capacitive loading reduces the phase

margin of amplifiers. The combination of the amplifier's output impedance and the capacitive load induces phase

lag. This results in either an underdamped pulse response or oscillation. To drive a heavier capacitive load, the

circuit in Figure 51 can be used.

Figure 51. Indirectly Driving a Capacitive Load Using Resistive Isolation

In Figure 51 , the isolation resistor R_ISOand the load capacitor C_Lform a pole to increase stability by adding more

phase margin to the overall system. The desired performance depends on the value of R_ISO. The bigger the R_ISO

resistor value, the more stable V_OUTwill be. Figure 52 is an output waveform of Figure 51 using 620Ω for R_ISO

and 510 pF for C_L..

Figure 52. Pulse Response of the LMV324 Circuit in Figure 51

The circuit in Figure 53 is an improvement to the one in Figure 51 because it provides DC accuracy as well as

AC stability. If there were a load resistor in Figure 51, the output would be voltage divided by R_ISOand the load

resistor. Instead, in Figure 53, R_Fprovides the DC accuracy by using feed-forward techniques to connect V_INto

R_L. Caution is needed in choosing the value of R_Fdue to the input bias current of theLMV321-N/LMV358-

N/LMV324-N. C_Fand R_ISOserve to counteract the loss of phase margin by feeding the high frequency

component of the output signal back to the amplifier's inverting input, thereby preserving phase margin in the

overall feedback loop. Increased capacitive drive is possible by increasing the value of C_F. This in turn will slow

down the pulse response.

Figure 53. Indirectly Driving A Capacitive Load with DC Accuracy

INPUT BIAS CURRENT CANCELLATION

The LMV321-N/LMV358-N/LMV324-N family has a bipolar input stage. The typical input bias current of LMV321-

N/LMV358-N/LMV324-N is 15 nA with 5V supply. Thus a 100 kΩ input resistor will cause 1.5 mV of error voltage.

By balancing the resistor values at both inverting and non-inverting inputs, the error caused by the amplifier's

input bias current will be reduced. The circuit in Figure 54 shows how to cancel the error caused by input bias

current.

TYPICAL SINGLE-SUPPLY APPLICATION CIRCUITS

Difference Amplifier

The difference amplifier allows the subtraction of two voltages or, as a special case, the cancellation of a signal

common to two inputs. It is useful as a computational amplifier, in making a differential to single-ended

conversion or in rejecting a common mode signal.

Figure 55. Difference Amplifier

Instrumentation Circuits

The input impedance of the previous difference amplifier is set by the resistors R₁, R₂, R₃, and R₄. To eliminate

the problems of low input impedance, one way is to use a voltage follower ahead of each input as shown in the

following two instrumentation amplifiers.

Three-Op-Amp Instrumentation Amplifier

The quad LMV324 can be used to build a three-op-amp instrumentation amplifier as shown in Figure 56.

Figure 56. Three-Op-Amp Instrumentation Amplifier

The first stage of this instrumentation amplifier is a differential-input, differential-output amplifier, with two voltage

followers. These two voltage followers assure that the input impedance is over 100 MΩ. The gain of this

instrumentation amplifier is set by the ratio of R₂/R₁. R₃should equal R₁, and R₄equal R₂. Matching of R₃to R₁

and R₄to R₂affects the CMRR. For good CMRR over temperature, low drift resistors should be used. Making R₄

slightly smaller than R₂and adding a trim pot equal to twice the difference between R₂and R₄will allow the

CMRR to be adjusted for optimum performance.

Two-Op-Amp Instrumentation Amplifier

A two-op-amp instrumentation amplifier can also be used to make a high-input-impedance DC differential

amplifier (Figure 57). As in the three-op-amp circuit, this instrumentation amplifier requires precise resistor

matching for good CMRR. R₄should equal R₁and, R₃should equal R₂.

Figure 57. Two-Op-Amp Instrumentation Amplifier

Single-Supply Inverting Amplifier

There may be cases where the input signal going into the amplifier is negative. Because the amplifier is

operating in single supply voltage, a voltage divider using R₃and R₄is implemented to bias the amplifier so the

input signal is within the input common-mode voltage range of the amplifier. The capacitor C₁is placed between

the inverting input and resistor R₁to block the DC signal going into the AC signal source, V_IN. The values of R₁

and C₁affect the cutoff frequency, fc = 1/2πR₁C₁.

As a result, the output signal is centered around mid-supply (if the voltage divider provides V⁺/2 at the non-

inverting input). The output can swing to both rails, maximizing the signal-to-noise ratio in a low voltage system.

Figure 58. Single-Supply Inverting Amplifier

ACTIVE FILTER

Simple Low-Pass Active Filter

The simple low-pass filter is shown in Figure 59. Its low-frequency gain (ω → 0) is defined by −R₃/R₁. This allows

low-frequency gains other than unity to be obtained. The filter has a −20 dB/decade roll-off after its corner

frequency fc. R₂should be chosen equal to the parallel combination of R₁and R₃to minimize errors due to bias

current. The frequency response of the filter is shown in Figure 60.

should have an open loop voltage gain at the highest frequency of interest at least 50 times larger than the gain

of the filter at this frequency. In addition, the selected op amp should have a slew rate that meets the following

The above resistor values are normalized values with ω_n= 1 rad/s and C₁= C₂= C_n= 1F. To scale the

scaling factor (k_f) and impedance scaling factor (k_m).

An adjustment to the scaling may be made in order to have realistic values for resistors and capacitors. The

2nd-Order High Pass Filter

A 2nd-order high pass filter can be built by simply interchanging those frequency selective components (R₁, R₂,

C₁, C₂) in the Sallen-Key 2nd-order active low pass filter. As shown in Figure 62, resistors become capacitors,

and capacitors become resistors. The resulted high pass filter has the same corner frequency and the same

maximum gain as the previous 2nd-order low pass filter if the same components are chosen.

amp, such as the LMV324 (Figure 63).

This circuit can simultaneously represent a low-pass filter, high-pass filter, and bandpass filter at three different

outputs. The equations for these functions are listed below. It is also called "Bi-Quad" active filter as it can

PULSE GENERATORS AND OSCILLATORS

A pulse generator is shown in Figure 64. Two diodes have been used to separate the charge and discharge

paths to capacitor C.

Figure 64. Pulse Generator

When the output voltage V_Ois first at its high, V_OH, the capacitor C is charged toward V_OHthrough R₂. The

voltage across C rises exponentially with a time constant τ = R₂C, and this voltage is applied to the inverting

input of the op amp. Meanwhile, the voltage at the non-inverting input is set at the positive threshold voltage

(V_TH+) of the generator. The capacitor voltage continually increases until it reaches V_TH+, at which point the

output of the generator will switch to its low, V_OLwhich 0V is in this case. The voltage at the non-inverting input is

switched to the negative threshold voltage (V_TH−) of the generator. The capacitor then starts to discharge toward

V_OLexponentially through R₁, with a time constant τ = R₁C. When the capacitor voltage reaches V_TH−, the output

of the pulse generator switches to V_OH. The capacitor starts to charge, and the cycle repeats itself.

CURRENT SOURCE AND SINK

The LMV321-N/LMV358-N/LMV324-N can be used in feedback loops which regulate the current in external PNP

transistors to provide current sources or in external NPN transistors to provide current sinks.

Fixed Current Source

A multiple fixed current source is shown in Figure 68. A voltage (V_REF= 2V) is established across resistor R₃by

the voltage divider (R₃and R₄). Negative feedback is used to cause the voltage drop across R₁to be equal to

V_REF. This controls the emitter current of transistor Q₁and if we neglect the base current of Q₁and Q₂,

essentially this same current is available out of the collector of Q₁.

Large input resistors can be used to reduce current loss and a Darlington connection can be used to reduce

errors due to the β of Q₁.

The resistor, R₂, can be used to scale the collector current of Q₂either above or below the 1 mA reference value.

COMPARATOR WITH HYSTERESIS

The LMV321-N/LMV358-N/LMV324-N can be used as a low power comparator. Figure 72 shows a comparator

with hysteresis. The hysteresis is determined by the ratio of the two resistors.

V_TH+= V_REF/(1+R ₁/R₂)+V_OH/(1+R₂/R₁)

V_TH−= V_REF/(1+R ₁/R₂)+V_OL/(1+R₂/R₁)

V_H= (V_OH−V_OL)/(1+R ₂/R₁)

(30)

(31)

(32)

where

V_TH+: Positive Threshold Voltage

V_TH−: Negative Threshold Voltage

V_OH: Output Voltage at High

V_OL: Output Voltage at Low

V_H: Hysteresis Voltage

Since LMV321-N/LMV358-N/LMV324-N have rail-to-rail output, the (V_OH−V_OL) is equal to V_S, which is the supply

voltage.

V_H= V_S/(1+R₂/R₁)

(33)

The differential voltage at the input of the op amp should not exceed the specified absolute maximum ratings.

For real comparators that are much faster, we recommend you use Texas Instruments's

LMV331/LMV93/LMV339, which are single, dual and quad general purpose comparators for low voltage

operation.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other

changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest

issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and

complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale

supplied at the time of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily

performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered

documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support

that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which

anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause

harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use

of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to

help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and

requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties

have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in

military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components

which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and

regulatory requirements in connection with such use.

TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of

non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
