GENERAL DESCRIPTION
The AD823 is a dual precision, 16 MHz, JFET input op amp
that can operate from a single supply of 3.0 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
50 mV of each rail for IOUT ≤ 100 µA, providing outstanding
output dynamic range.
An offset voltage of 800 µV maximum, an offset voltage drift of
2 µV/°C, input bias currents below 25 pA, and low input voltage
noise provide dc precision with source impedances up to a
Gigaohm. It provides 16 MHz, −3 dB bandwidth, −108 dB THD
@ 20 kHz, and a 22 V/µs slew rate with a low supply current of
2.6 mA per amplifier. The AD823 drives up to 500 pF of direct
capacitive load as a follower and provides an output current of
15 mA, 0.5 V from the supply rails. This allows the amplifier to
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 A/D drivers, high speed active
filters, and other low voltage, high dynamic range systems.
The AD823 is available over the industrial temperature range of
−40°C to +85°C and is offered in both 8-lead PDIP and 8-lead
SOIC packages.
