应用功能:Low Power, Low NoisePrecision FET Op Amp The AD795 is a low noise, precision, FET input operationalamplifier. It offers both the low voltage noise and low offset driftof a bipolar input op amp and the very low bias current of aFET-input device. The 1014 W common-mode impedanceinsures that input bias current is essentiallyindependentofcommon-mode voltage and supply voltage variations.
