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.

Good DC Performance

800 ꢁV Max Input Offset Voltage

2 ꢁV/ꢂC Typ Offset Voltage Drift

25 pA Max Input Bias Current

Low Noise

13 nV/÷Hz @ 10 kHz

No Phase Inversion

Offset voltage of 800 mV max, offset voltage drift of 2 mV/∞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/ms slew rate are provided with a low supply current of

800 mA 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.

APPLICATIONS

Battery-Powered Precision Instrumentation

Photodiode Preamps

Active Filters

12- to 14-Bit Data Acquisition Systems

Medical Instrumentation

Low Power References and Regulators

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.

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

The AD822 is offered in three varieties of 8-lead packages:

Plastic DIP, MSOP, and SOIC.
