Texas Instruments  POPA2182ID

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-friendlyarchitecture and controlled startup system. These features and excellent ac performance, combinedwith only 0.45 µV of offset voltage and 0.005 µV/°C of drift over temperature, makes the OPA2182 agreat choice for precision instrumentation, signal measurement, and active filtering applications.

The MUX-friendly input architecture prevents inrush current when applying large inputdifferential voltages that improves settling performance in multichannel systems. Moreover, thecontrolled startup system rejects any inrush current upon ramping up the supply rails, all whileproviding robust ESD protection during shipment, handling, and assembly.

The device is specified from –40°C to +125°C.
