The OPA735AID is a single CMOS zero-drift series Operational Amplifier uses auto-zeroing techniques to simultaneously provide low offset voltage (5μV maximum), near-zero drift over time and temperature. This miniature, high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing within 50mV of the rails. It is optimized for low-voltage, single-supply operation. Under logic control, the amplifier can be switched from normal operation to a standby current that is 9μA (maximum) and the output placed in a high-impedance state.
