OPA189IDGKR TI Instrumentation, OP Amps, Buffer Amps

The OPA189 is a zero-drift operational amplifier with ultra-low offset voltage of 3 µV maximum and drift of 0.02 µV/°C. It operates from 4.5 V to 36 V single supply (or ±2.25 V to ±18 V dual) with 14 MHz gain-bandwidth product and 20 V/µs slew rate. The device features low noise of 7.2 nV/√Hz and rail-to-rail output swing. The OPA189 uses proprietary auto-calibration techniques for precision over time and temperature. Quiescent current is 1.3 mA typical. Packaged in 8-pin VSSOP (DGK), this op-amp is optimal for precision bridge and sensor applications requiring low drift over temperature. Applications include bridge sensor amplifiers, thermocouple and RTD interfaces, medical instrumentation (ECG/EEG), and precision current sensing for industrial automation requiring high accuracy and low drift.
