OPA2189IDR TI Instrumentation, OP Amps, Buffer Amps
The OPA2189 is a dual zero-drift operational amplifier with ultra-low offset voltage of 3µV maximum and drift of 0.02µV/°C. It operates from 4.5V to 36V single supply (or ±2.25V to ±18V dual) with 14MHz gain-bandwidth product and 20V/µs slew rate. The device features low noise of 7.2nV/√Hz and rail-to-rail output swing. Selection is ideal for precision sensor conditioning 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.
