OPA180 - Texas Instruments

OPA180 Zero-Drift Operational Amplifiers

The OPA180, OPA2180 and OPA4180 operational amplifiers (op amps) use TI's proprietary zero-drift techniques to simultaneously provide low offset voltage (75 μV), and near zero-drift over time and temperature. These miniature, high-precision, lowquiescent-current op amps offer high input impedance and rail-to-rail output swing within 18 mV of the rails. The i.
