    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. The AD848 and AD849 are members of Analog Devices’ family of high speed op amps. This family includes, among others, the AD847 which is unity gain stable, with a gain bandwidth of 50 MHz. For more demanding applications, the AD840, AD841 and AD842 offer even greater precision and greater output current drive.
            The AD848 and AD849 have good dc performance. When operating with ± 5 V supplies, they offer open loop gains of 13 V/mV (AD848 with a 500 Ω load) and low input offset voltage of 1 mV maximum. Common-mode rejection is a minimum of 92 dB. Output voltage swing is ± 3 V even into loads as low as 150 Ω.
