Texas Instruments OPAx317/OPAx317-Q1 Zero-Drift Op Amps

Texas Instruments OPAx317 Precision Operational Amplifiers (Op Amps) are members of the Zero-Drift family of amplifiers. These amplifiers use a proprietary auto calibration technique to simultaneously provide low offset voltage (90µV max) and near-zero drift over time and temperature at only 35µA (max) of quiescent current. These TI op amps feature rail-to-rail input and output in addition to near flat 1/f noise, making this amplifier ideal for many applications, and much easier to design into a system. These TI devices are optimized for low-voltage operation as low as +1.8V (±0.9V) and up to +5.5V (±2.75V). The OPA317-Q1 devices are AEC-Q100 qualified for automotive applications.
