ADA4098-2BRMZ

ADA4098-2BRMZ is a dual robust, precision, rail-to-rail input and output operational amplifier (op-amp). The ADA4098-2 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. The unity gain is stable and can drive loads requiring upto 20mA per channel. This device can also drive capacitive loads as large as 200pF. 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.
