ADI AD843KN

Общее назначение34 МГц

Overview

The AD843KN is a fast settling, 34 MHz, CBFET input op amp. The AD843KN 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 AD843KN 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.

Unlike many high frequency amplifiers, the AD843KN requires no external compensation and it remains stable over its full operating 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.
