AD795JRZ

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 O 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 and tested maximum input voltage noise. It features 2 pA maximum input bias current and 500 µV maximum offset voltage, along with low supply current of 1.5 mA maximum. Furthermore, the AD795 features a guaranteed low input noise of 3.3 µV p-p (0.1 Hz to 10 Hz) and a 11 nV/vHz maximum noise level at 10 kHz. The AD795 has a fully specified and tested input offset voltage drift of only 10 µV/°C maximum. The AD795 is useful for many high input impedance, low noise applications. The AD795 is rated over the commercial tempera- ture range of 0°C to +70°C. The AD795 is available in an 8-lead SOIC package.
