Texas Instruments OPAx180/OPAx180-Q1 Zero-Drift Op Amps

Texas Instruments OPAx180/OPAx180-Q1 Zero-Drift Operational Amplifier uses zero-drift techniques to simultaneously provide low offset voltage (75μV) and near zero-drift (0.1μV/°C) over time and temperature. This miniature, high-precision, 525μA (max.) low quiescent current amplifier offers high input impedance, very low 1/f noise, and rail-to-rail output swing within 18mV of the rails. The input common-mode range includes the negative rail. Specified for operation from -40°C to 105°C, the OPAx180/OPAx180-Q1 Zero-Drift Operational Amplifier is well-suited for bridge amplifiers, strain gauges, test equipment, transducer applications, temperature measurement, electronic scales, medical instrumentation, resister thermal detectors, and precision active filters. The Texas Instruments OPAx180-Q1 devices are AEC-Q100 qualified for automotive applications.
