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.
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.
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.

Supply Voltage .................................................................................... +7V
Signal Input Terminals, Voltage(2) ........................... 0.5V to (V+) + 0.5V

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
amplifier per package.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
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.
