OPA180 Zero-Drift Operational Amplifier

OPA180 Zero-Drift Operational Amplifier

Texas Instruments' OPA180 operational amplifier uses zero-drift techniques to simultaneously provide low offset voltage (75 µV), 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 18 mV of the rails. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of 4.0 V to 36 V (±2 V to ±18 V).

The dual version is offered in VSSOP-8 and SOIC-8 packages. The quad is offered in SOIC-14 and TSSOP-14 packages. All versions are specified for operation from –40°C to 105°C.
