ADA4097-2BRMZ

ADA4097-2BRMZ is a dual robust, precision, rail-to-rail input and output operational amplifier (op-amp). This device features offset voltages of <lt/>60µV, input bias currents (IB) of <lt/>0.3nA, and can operate on single or split supplies that range from 3V to 50V. It draws 32.5µA of supply current per channel. The ADA4097-2 Over-The-Top™ input stages have robust input protection features for abusive environments. The inputs can tolerate upto 80V of differential voltage without damage or degradation to DC accuracy. The operating common-mode input range extends from rail to rail and beyond, upto 70V <gt/> –VS, independent of the +VS supply. It is used in applications such as industrial sensor conditioning, supply current sensing, battery and power supply monitoring, front-end amplifiers in abusive environments, 4mA to 20mA transmitters.
