Precision l-to-V converters GENERAL DESCRIPTION
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
FET-input device. The 1014 Ω common-mode impedance
insures that input bias current is essentially independent of
common-mode voltage and supply voltage variations.
The AD795 has both excellent dc performance and a guaranteed …
