AD848SQ/883B
数据手册.pdf高速，低功耗单片运算放大器 High Speed, Low Power Monolithic Op Amp
PRODUCT DESCRIPTION
The AD848 and AD849 are high speed, low power monolithic operational amplifiers. The AD848 is internally compensated so that it is stable for closed loop gains of 5 or greater. The AD849 is fully decompensated and is stable at gains greater than 24. The AD848 and AD849 achieve their combination of fast ac and good dc performance by utilizing Analog Devices’ junction isolated complementary bipolar CB process. This process enables these op amps to achieve their high speed while only requiring 4.8 mA of current from the power supplies.
