AD843JNZ, Быстродействующиq операционный усилитель 34МГц CBFET Fast Settling [DIP-8]

The AD843JNZ is a fast settling Operational Amplifier with CBFET input. The AD843 combines the low (0.6nA) input bias current characteristic of a FET input amplifier while still providing a 34MHz bandwidth and a 135ns settling time (to within 0.01% of final value for a 10 volt step). The AD843 is a member of the Analog Devices’ family of wide bandwidth operational amplifiers. This device is 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 250V/ms slew rate and 0.6nA input bias current of the AD843 ensure excellent performance in high speed sample-and-hold applications and in high speed integrators. This amplifier is also ideally suited for high bandwidth active filters and high frequency signal conditioning circuits.
