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 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.
