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 connected high, the amplifier is active. Connecting Enable low
disables the amplifier, and places the output in a highimpedance 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.
