6.3 Feature Description

The OPAx488 features a 48V operating and a 60V absolute maximum voltage to enable robust system designs. These operational amplifiers use a proprietary, periodic autocalibration technique to provide low input offset voltage and very low input offset voltage drift over time and temperature. The devices have several integrated features to help maintain a high level of precision through a variety of applications. These include a phase-reversal protection, EMI rejection, electrical overstress protection, and MUX-friendly inputs.
