Description

The AD795 is a low noise, precision, FET input operational amplifier. It offers both the low voltage noise and low offset drif of a bipolar input op amp and the very low bias current of a FET-input device. The 10 14 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 guaran- teed and tested maximum input voltage noise. It features 1 pA maximum input bias current and 250 V maximum offset volt age, along with low supply current of 1.5 mA max.Furthermore, the AD795 features a guaranteed low input noise of 2.5 V p-p (0.1 Hz to 10 Hz) and a 11 nV/Hz max noise level at 10 kHz. The AD795 has a fully specified and tested input offset voltage drift of only 3 V/°C max.

The AD795 is useful for many high input impedance, low noise applications. The AD795J and AD795K are rated over the commercial temperature range of 0°C to +70°C.The AD795 is available in 8-pin plastic mini-DIP and 8-pi surface mount (SOIC) packages.
