LM193/LM293/LM393/LM2903 Low Power Low Offset Voltage Dual Comparators

Check for Samples: LM193-N, LM2903-N, LM293-N, LM393-N

FEATURES

DESCRIPTION

The LM193 series consists of two independent

precision voltage comparators with an offset voltage

specification as low as 2.0 mV max for two

comparators which were designed specifically to

operate from a single power supply over a wide range

of voltages. Operation from split power supplies is

also possible and the low power supply current drain

is independent of the magnitude of the power supply

voltage. These comparators also have a unique

characteristic in that the input common-mode voltage

range includes ground, even though operated from a

single power supply voltage.

•

Application areas include limit comparators, simple

analog to digital converters; pulse, squarewave and

time delay generators; wide range VCO; MOS clock

timers; multivibrators and high voltage digital logic

gates. The LM193 series was designed to directly

interface with TTL and CMOS. When operated from

both plus and minus power supplies, the LM193

series will directly interface with MOS logic where

their low power drain is a distinct advantage over

standard comparators.

(1) Refer to RETS193AX for LM193AH military specifications and to RETS193X for LM193H military specifications.

(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.

(3) Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode

range, the comparator will provide a proper output state. The low input voltage state must not be less than −0.3V (or 0.3V below the

magnitude of the negative power supply, if used).

(4) This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of

the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is

also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go

to the V⁺voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive

and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than −0.3V.

(5) For operating at high temperatures, the LM393 and LM2903 must be derated based on a 125°C maximum junction temperature and a

thermal resistance of 170°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The

LM193/LM193A/LM293 must be derated based on a 150°C maximum junction temperature. The low bias dissipation and the “ON-OFF”

characteristic of the outputs keeps the chip dissipation very small (P_D≤100 mW), provided the output transistors are allowed to saturate.

(6) Short circuits from the output to V⁺can cause excessive heating and eventual destruction. When considering short circuits to ground,

the maximum output current is approximately 20 mA independent of the magnitude of V⁺.

APPLICATION HINTS

The LM193 series are high gain, wide bandwidth devices which, like most comparators, can easily oscillate if the

output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only

during the output voltage transition intervals as the comparator change states. Power supply bypassing is not

required to solve this problem. Standard PC board layout is helpful as it reduces stray input-output coupling.

Reducing the input resistors to < 10 kΩ reduces the feedback signal levels and finally, adding even a small

amount (1.0 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to

stray feedback are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-

output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse

waveform, with relatively fast rise and fall times, hysteresis is not required.

All input pins of any unused comparators should be tied to the negative supply.

The bias network of the LM193 series establishes a drain current which is independent of the magnitude of the

power supply voltage over the range of from 2.0 V_DCto 30 V_DC

It is usually unnecessary to use a bypass capacitor across the power supply line.

The differential input voltage may be larger than V⁺without damaging the device⁽¹⁾. Protection should be

provided to prevent the input voltages from going negative more than −0.3 V_DC(at 25°C). An input clamp diode

can be used as shown in Typical Applications.

The output of the LM193 series is the uncommitted collector of a grounded-emitter NPN output transistor. Many

collectors can be tied together to provide an output OR'ing function. An output pull-up resistor can be connected

to any available power supply voltage within the permitted supply voltage range and there is no restriction on this

voltage due to the magnitude of the voltage which is applied to the V⁺terminal of the LM193 package. The

output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used). The amount of

current which the output device can sink is limited by the drive available (which is independent of V⁺) and the β

of this device. When the maximum current limit is reached (approximately 16mA), the output transistor will come

out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the

approximately 60Ω r_SATof the output transistor. The low offset voltage of the output transistor (1.0mV) allows the

output to clamp essentially to ground level for small load currents.

⁽²⁾Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability

information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between

the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight

in homogeneous material)

⁽³⁾MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

NOTES:

www.ti.com

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.
