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.
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
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
.
APPLICATIONS HIGHLIGHTS
1. The high slew rate and fast settling time of the AD848 and
AD849 make them ideal for video instrumentation circuitry,
low noise pre-amps and line drivers.
2. In order to meet the needs of both video and data acquisition
applications, the AD848 and AD849 are optimized and
tested for
±5 V and ±15 V power supply operation.
3. Both amplifiers offer full power bandwidth greater than
20 MHz (for 2 V p-p with
±5 V supplies).
4. The AD848 and AD849 remain stable when driving any
capacitive load.
5. Laser wafer trimming reduces the input offset voltage to
1 mV maximum on all grades, thus eliminating the need for
external offset nulling in many applications.
6. The AD848 is an enhanced replacement for the LM6164
series and can function as a pin-for-pin replacement for
many high speed amplifiers such as the HA2520/2/5 and
EL2020 in applications where the gain is 5 or greater.
