8.1 Overview
The OPAx180-Q1 family of operational amplifiers combine precision offset and drift with excellent overall
performance, making them suitable for many precision applications. The precision offset drift of only 0.1 µV/°C
provides stability over the entire temperature range. In addition, the devices offer excellent overall performance
with high CMRR, PSRR, and A_OL. As with all amplifiers, applications with noisy or
high-impedance power supplies require decoupling capacitors close to the device pins. In most cases, 0.1-µF
capacitors are adequate.
