Texas Instruments OPA189
The OPA189, OPA2189, and OPA4189 (OPAx189) high-precision operational amplifiers are ultra-low noise, fast-settling, zero-drift devices that provide railto-rail output operation and feature a unique MUXfriendly architecture and controlled start-up system. These features and excellent ac performance, combined with only 0.4 µV of offset voltage and 0.005µV/°C of drift over temperature for the singlechannel version, make the OPAx189 a great choice for precision instrumentation, signal measurement, and active filtering applications.| Part No. | OPA189 |
