GENERAL DESCRIPTION
The AD822-EP is a dual precision, low power FET input op
amp that can operate from a single supply of 5 V to 30 V or dual
supplies of ±2.5 V to ±15 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.

AD822-EP
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.

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.

VOL − VEE is defined as the difference between the lowest possible output voltage (VOL) and the negative voltage supply rail (VEE). VCC − VOH is defined as the difference
between the highest possible output voltage (VOH) and the positive supply voltage (VCC).
