0.05µV/°C max, SINGLE-SUPPLYCMOS OPERATIONAL AMPLIFIERS
Zerø-Drift Series
FEATURES LOW OFFSET VOLTAGE: 5µV (max) ZERO DRIFT: 0.05µV/°C (max) QUIESCENT CURRENT: 285µA SINGLE-SUPPLY OPERATION SINGLE AND DUAL VERSIONS SHUTDOWN MicroSIZE PACKAGES
DESCRIPTIONThe OPA334 and OPA335 series of CMOS operationalamplifiers use auto-zeroing techniques to simultaneouslyprovide very low offset voltage (5µV max), and near-zero driftover time and temperature. These miniature, high-precision,low quiescent current amplifiers offer high input impedanceand 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-supplyoperation.
The OPA334 family includes a shutdown mode. Under logiccontrol, the amplifiers can be switched from normal operationto a standby current of 2µA. When the Enable pin is con-nected high, the amplifier is active. Connecting Enable lowdisables the amplifier, and places the output in a high-impedance state.
The OPA334 (single version with shutdown) comes inMicroSIZE SOT23-6. The OPA335 (single version withoutshutdown) 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 inthe MSOP-8 and SO-8 packages. All versions are specifiedfor operation from –40°C to +125°C.

APPLICATIONS INFORMATIONThe OPA334 and OPA335 series op amps are unity-gainstable and free from unexpected output phase reversal. Theyuse auto-zeroing techniques to provide low offset voltageand very low drift over time and temperature.
Good layout practice mandates use of a 0.1µF capacitorplaced closely across the supply pins.
For lowest offset voltage and precision performance, circuitlayout and mechanical conditions should be optimized. Avoidtemperature gradients that create thermoelectric (Seebeck)effects in thermocouple junctions formed from connectingdissimilar conductors. These thermally-generated potentialscan be made to cancel by assuring that they are equal onboth input terminals.
• Use low thermoelectric-coefficient connections (avoid dis-similar metals).
• Thermally isolate components from power supplies orother heat-sources.
• Shield op amp and input circuitry from air currents, such ascooling 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 onmaterials used.
OPERATING VOLTAGE
The OPA334 and OPA335 series op amps operate over apower-supply range of +2.7V to +5.5V (±1.35V to ±2.75V).Supply voltages higher than 7V (absolute maximum) canpermanently damage the amplifier. Parameters that varyover supply voltage or temperature are shown in the TypicalCharacteristics section of this data sheet.
OPA334 ENABLE FUNCTION
The enable/shutdown digital input is referenced to the V–supply voltage of the amp. A logic high enables the op amp. Avalid logic high is defined as > 75% of the total supply voltage.The valid logic high signal can be up to 5.5V above the negativesupply, independent of the positive supply voltage. A validlogic low is defined as < 0.8V above the V– supply pin. If dualor split power supplies are used, be sure that logic input signalsare properly referred to the negative supply voltage. TheEnable pin must be connected to a valid high or low voltage, ordriven, not left open circuit.
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 greatlyreduce the average current and extend battery life.
The enable time is 150µs, which includes one full auto-zerocycle required by the amplifier to return to VOS accuracy.Prior to this time, the amplifier functions properly, but withunspecified offset voltage.
Disable time is 1µs. When disabled, the output assumes ahigh-impedance state. This allows the OPA334 to be oper-ated as a gated amplifier, or to have the output multiplexedonto a common analog output bus.
INPUT VOLTAGE
The input common-mode range extends from (V–) – 0.1V to(V+) – 1.5V. For normal operation, the inputs must be limitedto this range. The common-mode rejection ratio is only validwithin the valid input common-mode range. A lower supplyvoltage results in lower input common-mode range; there-fore, attention to these values must be given when selectingthe input bias voltage. For example, when operating on asingle 3V power supply, common-mode range is from 0.1Vbelow ground to half the power-supply voltage.

Current-limiting resistor required if input voltage exceeds supply rails by≥ 0.5V.
Normally, input bias current is approximately 70pA; however,input voltages exceeding the power supplies can causeexcessive current to flow in or out of the input pins. Momen-tary voltages greater than the power supply can be toleratedif the input current is limited to 10mA. This is easily accom-plished with an input resistor, as shown in Figure 1.
INTERNAL OFFSET CORRECTION
The OPA334 and OPA335 series op amps use an auto-zerotopology with a time-continuous 2MHz op amp in the signalpath. This amplifier is zero-corrected every 100µs using aproprietary technique. Upon power-up, the amplifier requiresone full auto-zero cycle of approximately 100µs to achievespecified VOS accuracy. Prior to this time, the amplifierfunctions properly but with unspecified offset voltage.
This design has remarkably little aliasing and noise. Zerocorrection occurs at a 10kHz rate, but there is virtually nofundamental noise energy present at that frequency. For allpractical purposes, any glitches have energy at 20MHz orhigher and are easily filtered, if required. Most applicationsare not sensitive to such high-frequency noise, and nofiltering is required.
Unity-gain operation demands that the auto-zero circuitrycorrect 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 berequired to achieve full accuracy. This behavior is shown inthe typical characteristic section, see Settling Time vs Closed-Loop Gain.
ACHIEVING OUTPUT SWING TO THE OP AMP’SNEGATIVE RAIL
Some applications require output voltage swing from 0V to apositive full-scale voltage (such as +2.5V) with excellentaccuracy. With most single-supply op amps, problems arisewhen the output signal approaches 0V, near the lower output
FIGURE 2. Op Amp with Pull-Down Resistor to AchieveVOUT = Ground.
swing limit of a single-supply op amp. A good single-supplyop amp may swing close to single-supply ground, but will notreach ground. The output of the OPA334 or OPA335 can bemade to swing to ground, or slightly below, on a single-supply power source. To do so requires use of anotherresistor and an additional, more negative, power supply thanthe op amp’s negative supply. A pull-down resistor may beconnected between the output and the additional negativesupply to pull the output down below the value that the outputwould otherwise achieve, as shown in Figure 2.
The OPA334 and OPA335 have an output stage that allowsthe output voltage to be pulled to its negative supply rail, orslightly below using the above technique. This technique onlyworks with some types of output stages. The OPA334 andOPA335 have been characterized to perform well with thistechnique. Accuracy is excellent down to 0V and as low as–2mV. Limiting and non-linearity occurs below –2mV, butexcellent accuracy returns as the output is again drivenabove –2mV. Lowering the resistance of the pull-down resis-tor will allow the op amp to swing even further below thenegative rail. Resistances as low as 10kΩ can be used toachieve excellent accuracy down to –10mV.
LAYOUT GUIDELINES
Attention to good layout practices is always recommended.Keep traces short. When possible, use a PCB ground planewith surface-mount components placed as close to the de-vice pins as possible. Place a 0.1µF capacitor closely acrossthe supply pins. These guidelines should be applied through-out the analog circuit to improve performance and providebenefits such as reducing the EMI (electromagnetic-interfer-ence) susceptibility.
