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 startup 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 startup 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.
