    The AD795 is a low noise, precision, FET input operational
    amplifier. It offers both the low voltage noise and low offset drift
    of a bipolar input op amp and the very low bias current of a FETinput device. The 1014 О© common-mode impedance insures
    that input bias current is essentially independent of commonmode voltage and supply voltage variations.
    The AD795 has both excellent dc performance and a guaranteed
    and tested maximum input voltage noise. It features 2 pA ...
