Overview
The AD845KNZ is a fast, precise, N-channel JFET input, monolithic operational amplifier produced by Analog Devices Inc. It is fabricated using Analog Devices' complementary bipolar (CB) process, making it suitable for upgrading many existing designs that use BiFET or FET input hybrid amplifiers and, in some cases, those which use bipolar input op-amps.
