Texas Instruments OPA317 / 2317 / 4317 Zero-Drift Op Amps

TI OPA317/2317/4317 Zero-Drift Op Amps

Texas Instruments OPA317 (1-channel), OPA2317 (2-channel), and OPA4317 (four-channel) precision operational amplifiers (op amps) are members of the Zero-Drift family of amplifiers that 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 +1.8 V (±0.9 V) and up to +5.5 V (±2.75 V).
