OPA189IDR TI Instrumentation, OP Amps, Buffer Amps

The OPA189IDR is a single zero-drift operational amplifier from Texas Instruments featuring ultra-low offset voltage of 3 µV (max) and a unique offset drift of 0.02 µV/°C. It operates over a wide supply range of 4.5V to 36V (or ±2.25V to ±18V) and offers a gain bandwidth product of 14MHz with a high slew rate of 20 V/µs. The device provides rail-to-rail output swing, low noise of 2.5 µVp-p (0.1Hz to 10Hz), and high CMRR and PSRR of 140 dB. Housed in an 8-pin SOIC (D) package, it operates over -40°C to 125°C. Applications include precision data acquisition systems, bridge amplifiers for weigh scales, thermocouple amplifiers, medical instrumentation, and high-resolution test equipment requiring ultra-low offset and drift over temperature.
