0.05uV/C Max, Single-Supply CMOS Op Amps Zero-Drift

The OPA334 and OPA335 series of CMOS Operational Amplifiers use auto-zeroing techniques to simultaneously provide very low offset voltage (5??V 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 2??A. When the Enable pin is connected 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 40C to +125C. By Texas Instruments
