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.

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.
