ADI AD795JRZ

J-FET

Overview

The AD795JRZ is a low noise precision single FET input Operational Amplifier 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 10¹⁴R common-mode impedance insures that input bias current is essentially independent of common- mode voltage and supply voltage variations. The AD795JRZ has both excellent DC performance and a guaranteed and tested maximum input voltage noise. It features 2pA maximum input bias current and 500µV maximum offset voltage, along with low supply current of 1.5mA maximum. Furthermore, the AD795JRZ features a guaranteed low input noise of 3.3µVp-p (0.1 to 10Hz) and a 11nV/√Hz maximum noise level at 10kHz. The AD795JRZ has a fully specified and tested input offset voltage drift of only 10µV/°C maximum. The AD795JRZ is useful for many high input impedance and low noise applications.
