The ADA4098-1 and ADA4098-2 draw 165 µA of supply current per channel. The ADA4098-1 and ADA4098-2 Over-The-Top™ input stages have robust input protection Features for abusive environments. The inputs can tolerate up to 80 V of differential voltage without damage or degradation to dc accuracy. The operating mon-mode input range extends from rail-to-rail and beyond, up to 70 V > - VS, independent of the +VS supply. The ADA4098-1 and ADA4098-2 are...
