PRODUCT DESCRIPTION
The AD822 is a dual precision, low power FET input op amp
that can operate from a single supply of 3.0 V to 36 V or dual
supplies of
±
1.5 V to
±
18 V. It has true single-supply capability
with an input voltage range extending below the negative rail,
allowing the AD822 to accommodate input signals below ground
in the Single-Supply Mode. Output voltage swing extends to within
10 mV of each rail providing the maximum output dynamic range.
Offset voltage of 800
m
V max, offset voltage drift of 2

C,
input bias currents below 25 pA, and low input voltage noise
provide dc precision with source impedances up to a Gigaohm.
1.8 MHz unity gain bandwidth, –93 dB THD at 10 kHz,
and 3 V/
m
s slew rate are provided with a low supply current of
800
m
A per amplifier. The AD822 drives up to 350 pF of direct
capacitive load as a follower and provides a minimum output
current of 15 mA. This allows the amplifier to handle a wide
range of load conditions. Its combination of ac and dc perfor-
mance, plus the outstanding load drive capability, results in an
exceptionally versatile amplifier for the single-supply user.
The AD822 is available in two performance grades. The A and
B grades are rated over the industrial temperature range of
–40
∞
C to +85
∞
C.
The AD822 is offered in three varieties of 8-lead packages:
Plastic DIP, MSOP, and SOIC.
