The AD843 is a fast settling, 34 MHz, CBFET input op amp. The AD843 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 AD843 is a member of the Analog Devices’ family of wide bandwidth operational amplifi- ers. These devices are fabricated using Analog Devices’ junction isolated complementary bipolar (CB) process. This process per- mits a combination of dc precision and wideband ac perform- ance previously unobtainable in a monolithic op amp. The 250 V/µs slew rate and 0.6 nA 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 fre- quency signal conditioning circuits. Unlike many high frequency amplifiers, the AD843 requires no external compensation and it remains stable over its full operat- ing temperature range. It is available in five performance grades: the AD843J and AD843K are rated over the commercial temperature range of 0°C to +70°C. The AD843A and AD843B are rated over the industrial temperature range of –40°C to +85°C. The AD843S is rated over the military temperature range of –55°C to +125°C and is available processed to MIL-STD-883B, Rev. C.
