Texas Instruments OPA180 Zero-Drift Operational Amplifiers
Texas Instruments OPA180 Zero-Drift Operational Amplifier uses zero-drift technology to provide both low offset voltage (75μV) and near-zero drift (0.1μV/°C) over time and temperature. This tiny, high precision, 525µA (max) low quiescent current amplifier offers high input impedance, very low 1/f noise, and rail-to-rail outputs that swing within 18mV of the supply rails. The input common-mode range includes the negative rail. The OPA180 zero-drift operational amplifier is rated over the -40°C to 105°C temperature range and is ideal for bridge amplifiers, strain gauges, test equipment, frequency converter applications, temperature measurement, electronic scales, medical devices, resistance temperature detectors , Precision active filters, etc.CHARACTERISTIC
