AD845KNZ Datasheet PDF - ADI

The AD845KNZ is a precision monolithic Operational Amplifier with N channel JFET input. It is fabricated using complementary bipolar (CB) process. Advanced laser-wafer trimming technology enables the very low input offset voltage and offset voltage drift performance to be realized. This precision, when coupled with a slew rate of 100V/ms, a stable unity gain bandwidth of 16MHz and a settling time of 350ns to 0.01%, while driving a parallel load of 100pF and 500R, represents a combination of features unmatched by any FET input IC amplifier. The AD845 can easily be used to upgrade many existing designs that use BiFET or FET input hybrid amplifier and in some cases, those which use bipolar input op amps. The AD845 is ideal for use in applications such as active filters, high speed integrators, photodiode preamps, sample-and-hold amplifiers, log amplifiers and for buffering A/D and D/A converters.
