The OPAx182 family of operational amplifiers combine precision offset and drift with excellent overall performance, making these devices a great choice for many precision applications. The precision offset drift of only 0.005 µV/°C provides stability over the entire temperature range. In addition, these devices offer excellent linear performance with high CMRR, PSRR, and AOL. 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. See the Layout Guidelines section for details and a layout example.
The OPAx182 are zero-drift, MUX-friendly, rail-to-rail output operational amplifiers. The devices operate from 4.5 V to 36 V, are unity-gain stable, and a great choice for a wide range of general-purpose and precision applications. The zero-drift architecture provides ultra-low input offset voltage and near-zero input offset voltage drift over temperature and time. This choice of architecture also offers outstanding ac performance, such as ultra-low broadband noise, zero flicker noise, and outstanding distortion performance when operating below the chopper frequency.
