PRODUCT 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 10
14
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 guaran-
teed and tested maximum input voltage noise. It features 1 pA
maximum input bias current and 250
µV 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
µV 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
µV/°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-pin
surface mount (SOIC) packages.
