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 performance, 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 grade
and B grade are rated over the industrial temperature range of
−40°C to +85°C.
The
AD822
is offered in three varieties of 8-lead packages:
PDIP, MSOP, and SOIC_N.

This is a functional specification. Amplifier bandwidth decreases when the input common-mode voltage is driven in the range (V+ − 1 V) to V+. Common-mode error
voltage is typically less than 5 mV with the common-mode voltage set at 1 V below the positive supply.
