0.05µV/°C max, SINGLE-SUPPLY
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-
tion to complete device failure. Precision integrated circuits
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.
Exposure to absolute maximum conditions for extended periods may de-
grade device reliability. These are stress ratings only, and functional opera-
tion of the device at these, or any other conditions beyond those specified,
is not implied. (2) Input terminals are diode-clamped to the power-supply
rails. Input signals that can swing more than 0.5V beyond the supply rails
should be current-limited to 10mA or less. (3) Short-circuit to ground, one

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 VOS accuracy.
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.

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 VOS accuracy. Prior to this time, the amplifier
functions properly but with unspecified offset voltage.
FIGURE 2. Op Amp with Pull-Down Resistor to Achieve
VOUT = 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
