CMOS OPERATIONAL AMPLIFIERS

Zerø-Drift Series

FEATURES

DESCRIPTION

The OPA334 and OPA335 series of CMOS operational

amplifiers use auto-zeroing techniques to simultaneously

provide very low offset voltage (5µV max), and near-zero drift

over time and temperature. These miniature, high-precision,

low quiescent current amplifiers offer high input impedance

and rail-to-rail output swing. Single or dual supplies as low as

+2.7V (±1.35V) and up to +5.5V (±2.75V) may be used.

These op amps are optimized for low-voltage, single-supply

operation.

● LOW OFFSET VOLTAGE: 5µV (max)

● ZERO DRIFT: 0.05µV/°C (max)

● QUIESCENT CURRENT: 285µA

● SINGLE-SUPPLY OPERATION

● SINGLE AND DUAL VERSIONS

● SHUTDOWN

● MicroSIZE PACKAGES

The OPA334 family includes a shutdown mode. Under logic

control, the amplifiers can be switched from normal operation

to a standby current of 2µA. When the Enable pin is con-

nected high, the amplifier is active. Connecting Enable low

disables the amplifier, and places the output in a high-

impedance state.

APPLICATIONS

● TRANSDUCER APPLICATIONS

● TEMPERATURE MEASUREMENT

● ELECTRONIC SCALES

● MEDICAL INSTRUMENTATION

● BATTERY-POWERED INSTRUMENTS

● HANDHELD TEST EQUIPMENT

The OPA334 (single version with shutdown) comes in

MicroSIZE SOT23-6. The OPA335 (single version without

shutdown) is available in SOT23-5, and SO-8. The OPA2334

(dual version with shutdown) comes in MicroSIZE MSOP-10.

The OPA2335 (dual version without shutdown) is offered in

the MSOP-8 and SO-8 packages. All versions are specified

for operation from –40°C to +125°C.

ESD damage can range from subtle performance degrada-

may be more susceptible to damage because very small

parametric changes could cause the device not to meet its

published specifications.

NOTES: (1) Stresses above these ratings may cause permanent damage.

OPA334 ENABLE FUNCTION

APPLICATIONS INFORMATION

The enable/shutdown digital input is referenced to the V–

supply voltage of the amp. A logic high enables the op amp. A

valid logic high is defined as > 75% of the total supply voltage.

Thevalidlogichighsignalcanbeupto5.5Vabovethenegative

supply, independent of the positive supply voltage. A valid

logic low is defined as < 0.8V above the V– supply pin. If dual

orsplitpowersuppliesareused,besurethatlogicinputsignals

are properly referred to the negative supply voltage. The

Enable pin must be connected to a valid high or low voltage, or

driven, not left open circuit.

The OPA334 and OPA335 series op amps are unity-gain

stable and free from unexpected output phase reversal. They

use auto-zeroing techniques to provide low offset voltage

and very low drift over time and temperature.

Good layout practice mandates use of a 0.1µF capacitor

placed closely across the supply pins.

For lowest offset voltage and precision performance, circuit

layout and mechanical conditions should be optimized. Avoid

temperature gradients that create thermoelectric (Seebeck)

effects in thermocouple junctions formed from connecting

dissimilar conductors. These thermally-generated potentials

can be made to cancel by assuring that they are equal on

both input terminals.

The logic input is a high-impedance CMOS input, with sepa-

rate logic inputs provided on the dual version. For battery-

operated applications, this feature can be used to greatly

reduce the average current and extend battery life.

• Use low thermoelectric-coefficient connections (avoid dis-

similar metals).

The enable time is 150µs, which includes one full auto-zero

cycle required by the amplifier to return to V_OSaccuracy.

Prior to this time, the amplifier functions properly, but with

unspecified offset voltage.

• Thermally isolate components from power supplies or

other heat-sources.

Disable time is 1µs. When disabled, the output assumes a

high-impedance state. This allows the OPA334 to be oper-

ated as a gated amplifier, or to have the output multiplexed

onto a common analog output bus.

• Shield op amp and input circuitry from air currents, such as

cooling fans.

Following these guidelines will reduce the likelihood of junc-

tions being at different temperatures, which can cause ther-

moelectric voltages of 0.1µV/°C or higher, depending on

materials used.

INPUT VOLTAGE

The input common-mode range extends from (V–) – 0.1V to

(V+) – 1.5V. For normal operation, the inputs must be limited

to this range. The common-mode rejection ratio is only valid

within the valid input common-mode range. A lower supply

voltage results in lower input common-mode range; there-

fore, attention to these values must be given when selecting

the input bias voltage. For example, when operating on a

single 3V power supply, common-mode range is from 0.1V

below ground to half the power-supply voltage.

OPERATING VOLTAGE

The OPA334 and OPA335 series op amps operate over a

power-supply range of +2.7V to +5.5V (±1.35V to ±2.75V).

Supply voltages higher than 7V (absolute maximum) can

permanently damage the amplifier. Parameters that vary

over supply voltage or temperature are shown in the Typical

Characteristics section of this data sheet.

SBOS245D

Normally, input bias current is approximately 70pA; however,

input voltages exceeding the power supplies can cause

excessive current to flow in or out of the input pins. Momen-

tary voltages greater than the power supply can be tolerated

if the input current is limited to 10mA. This is easily accom-

plished with an input resistor, as shown in Figure 1.

swing limit of a single-supply op amp. A good single-supply

op amp may swing close to single-supply ground, but will not

reach ground. The output of the OPA334 or OPA335 can be

made to swing to ground, or slightly below, on a single-

supply power source. To do so requires use of another

resistor and an additional, more negative, power supply than

the op amp’s negative supply. A pull-down resistor may be

connected between the output and the additional negative

supply to pull the output down below the value that the output

would otherwise achieve, as shown in Figure 2.

INTERNAL OFFSET CORRECTION

The OPA334 and OPA335 series op amps use an auto-zero

topology with a time-continuous 2MHz op amp in the signal

path. This amplifier is zero-corrected every 100µs using a

proprietary technique. Upon power-up, the amplifier requires

one full auto-zero cycle of approximately 100µs to achieve

specified V_OSaccuracy. Prior to this time, the amplifier

functions properly but with unspecified offset voltage.

FIGURE 2. Op Amp with Pull-Down Resistor to Achieve

V_OUT= Ground.

The OPA334 and OPA335 have an output stage that allows

the output voltage to be pulled to its negative supply rail, or

slightly below using the above technique. This technique only

works with some types of output stages. The OPA334 and

OPA335 have been characterized to perform well with this

technique. Accuracy is excellent down to 0V and as low as

–2mV. Limiting and non-linearity occurs below –2mV, but

excellent accuracy returns as the output is again driven

above –2mV. Lowering the resistance of the pull-down resis-

tor will allow the op amp to swing even further below the

negative rail. Resistances as low as 10kΩ can be used to

achieve excellent accuracy down to –10mV.

This design has remarkably little aliasing and noise. Zero

correction occurs at a 10kHz rate, but there is virtually no

fundamental noise energy present at that frequency. For all

practical purposes, any glitches have energy at 20MHz or

higher and are easily filtered, if required. Most applications

are not sensitive to such high-frequency noise, and no

filtering is required.

Unity-gain operation demands that the auto-zero circuitry

correct for common-mode rejection errors of the main ampli-

fier. Because these errors can be larger than 0.01% of a full-

scale input step change, one calibration cycle (100µs) can be

required to achieve full accuracy. This behavior is shown in

the typical characteristic section, see Settling Time vs Closed-

Loop Gain.

LAYOUT GUIDELINES

Attention to good layout practices is always recommended.

Keep traces short. When possible, use a PCB ground plane

with surface-mount components placed as close to the de-

vice pins as possible. Place a 0.1µF capacitor closely across

the supply pins. These guidelines should be applied through-

out the analog circuit to improve performance and provide

benefits such as reducing the EMI (electromagnetic-interfer-

ence) susceptibility.

ACHIEVING OUTPUT SWING TO THE OP AMP’S

NEGATIVE RAIL

Some applications require output voltage swing from 0V to a

positive full-scale voltage (such as +2.5V) with excellent

accuracy. With most single-supply op amps, problems arise

when the output signal approaches 0V, near the lower output
