NCx2191x Precision Operational Amplifiers onsemi NCx2191x Precision Operational Amplifiers offer low offset voltage and zero drift over temperature. The NCx2191x Amplifiers feature a maximum offset voltage of 25V and an input common-mode voltage range that includes ground. This makes the NCx2191x Amps well-suited for applications where precision is required, such as low side current sensing and interfacing with sensors. Automotive qualified options are available under the NCV prefix.
