0.05??V/°C Max, Single-Supply CMOS Operational Amplifier Zero-Drift

The OPA734 and OPA735 series of CMOS Operational Amplifiers use auto-zeroing techniques to simultaneously provide 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 within 50mV of the rails. Either single or bipolar supplies CAN be used in the range of +2.7V to +12V (1.35V to 6V). They are optimized for low-voltage, single-supply operation. The OPA734 family includes a shutdown mode. Under Logic control, the Amplifiers CAN be switched from normal operation to a standby current that is 9??A (max) and the output placed in a high-impedance state. The single version is available in the MicroSIZE SOT23-5 (SOT23-6 for shutdown version) and the SO-8 packages. The dual version is available in the MSOP-8 and SO-8 packages (MSOP-10 only for the shutdown version). All versions are specified for operation from 40C to +85C. By Texas Instruments
