AD843JN

Product Summary

The AD843JN is a fast settling, 34 MHz, CBFET input op amp. The AD843JN combines the low (0.6 nA) input bias currents characteristic of a FET input amplifier while still providing a 34 MHz bandwidth and a 135 ns settling time (to within 0.01% of final value for a 10 volt step). The AD843JN is a member of the Analog Devices’family of wide bandwidth operational amplifiers. These devices are fabricated using Analog Devices’ junction isolated complementary bipolar (CB) process. This process permits a combination of dc precision and wideband ac performance previously unobtainable in a monolithic op amp. The applications of the AD843JN include high speed sample-and-hold amplifiers, high bandwidth active filters, high speed integrators, high frequency signal conditioning.
