The AD822-EP 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-EP operates over the military temperature range of
−55°C to +125°C.
The AD822-EP is offered in an 8-lead SOIC_N package.
Full details about this enhanced product are available in the
AD822
data sheet, which should be consulted in conjunction
with this data sheet.

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.
