a High Speed, Low Power
Monolithic Op Amp
AD848/AD849 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. AD848/49 6 OUTPUT +IN 3 …
