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.

GOOD DC PERFORMANCE

800 ␮V Max Input Offset Voltage

LOW NOISE

13 nV/ √Hz @ 10 kHz

NO PHASE INVERSION

Offset voltage of 800 µV max, 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.

1.8 MHz unity gain bandwidth, –93 dB T HD at 10 kHz and

3 V/µs slew rate are provided with a low supply current of

800 µA per amplifier. T he AD822 drives up to 350 pF of direct

capacitive load as a follower, and provides a minimum output

current of 15 mA. T his allows the amplifier to handle a wide

range of load conditions. T his combination of ac and dc

performance, plus the outstanding load drive capability, results

in an exceptionally versatile amplifier for the single supply user.

T he AD822 is available in four performance grades. T he A and

B grades are rated over the industrial temperature range of

–40°C to +85°C. T here is also a 3 volt grade—the AD822A-3V,

rated over the industrial temperature range. T he mil grade is

rated over the military temperature range of –55°C to +125°C

and is available processed on standard military drawing.

T he 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

T he AD822 is offered in three varieties of 8-pin package: plastic

DIP, hermetic cerdip and surface mount (SOIC) as well as die

form.
