AD822–SPECIFICATIONS
AD822
NOT ES
1See standard military drawing for 883B specifications.
2T his is a functional specification. Amplifier bandwidth decreases when the input common-mode voltage is driven in the range (+V S – 1 V) to +VS.
Common-mode error voltage is typically less than 5 mV with the common-mode voltage set at 1 volt below the positive supply.
3VOL–VEE is defined as the difference between the lowest possible output voltage (VOL) and the minus voltage supply rail (VEE).
VCC–VOH is defined as the difference between the highest possible output voltage (VOH ) and the positive supply voltage (VCC).
Specifications subject to change without notice.
CAUTIO N
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD822 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

an extended period can result in device burnout. T o ensure
proper operation, it is important to observe the derating curves

While the AD822 is internally short circuit protected, this may not
be sufficient to guarantee that the maximum junction temperature
is not exceeded under all conditions. With power supplies ±12
volts (or less) at an ambient temperature of +25°C or less, if the
output node is shorted to a supply rail, then the amplifier will not
be destroyed, even if this condition persists for an extended period.

T he maximum power that can be safely dissipated by the AD822 is
limited by the associated rise in junction temperature. For plastic
packages, the maximum safe junction temperature is 145°C. For
the cerdip packages, the maximum junction temperature is 175°C.
If these maximums are exceeded momentarily, proper circuit
