The OPA2182 high-precision operational amplifier is an ultra-low noise, fast-settling, zero-drift device that provides rail-to-rail output operation and features a unique MUX-friendly architecture and controlled start-up system. These features and excellent ac performance, combined with only 0.45 µV of offset voltage and 0.003 µV/°C of drift over temperature, makes the OPA2182 a great choice for data acquisition, battery test, analog input modules, weigh scales, and any other systems requiring high dc precision and low noise.
The MUX-friendly input architecture prevents inrush current when applying large input differential voltages that improves settling performance in multichannel systems. Moreover, the controlled start-up system rejects any inrush current upon ramping up the supply rails, all while providing robust ESD protection during shipment, handling, and assembly.
The device is specified from –40°C to +125°C.
