GENERAL DESCRIPTION
The AD823A is a dual precision, 17 MHz, JFET input op amp
manufactured in the extra fast complementary bipolar (XFCB)
process. The AD823A can operate from a single supply of 3 V
to 36 V or from dual supplies of ±1.5 V to ±18 V. It has true
single-supply capability with an input voltage range extending
below ground in single-supply mode. Output voltage swing extends
to within 20 mV of each rail for IOUT ≤ 100 μA, providing
outstanding output dynamic range. It also has a linear output
current of 40 mA, 0.5 V from the supply rails.
An offset voltage of 700 μV maximum, an offset voltage drift of
1 μV/°C, and typical input bias currents of 0.3 pA provide dc
precision with source impedances up to 1 GΩ. The AD823A
provides 17 MHz, 3 dB bandwidth, and a 30 V/μs slew rate with
a low supply current of only 2.6 mA per amplifier. It also provides
low input voltage noise of 14 nV/√Hz and 108 dB SFDR at
20 kHz. The AD823A has low input capacitances (0.6 pF differ-
ential and 1.3 pF common mode) and drives more than 500 pF
of direct capacitive load as a follower. This lets the amplifier
handle a wide range of load conditions.

This combination of ac and dc performance, plus the outstanding
load drive capability, results in an exceptionally versatile ampli-
fier for applications such as ADC drivers, high speed active filters,
and other low voltage, high dynamic range systems.
The AD823A is available over the industrial temperature range
of 40°C to +85°C and is offered in an 8-lead SOIC package and
an 8-lead MSOP package.
