GENERAL DESCRIPTION
The AD822 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.

Figure 2. Input Voltage Noise vs. Frequency
Offset voltage of 800 μV maximum, 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.
The 1.8 MHz unity-gain bandwidth, –93 dB THD at 10 kHz,
and 3 V/μs slew rate are provided with a low supply current of
800 μA per amplifier.
