REV. A

NOTES

Common-mode error voltage is typically less than 5 mV with the common-mode voltage set at 1 volt below the positive supply.

Specifications subject to change without notice.

WARNING!

ESD SENSITIVE DEVICE

CAUTION

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. Therefore, proper ESD

precautions are recommended to avoid performance degradation or loss of functionality.

operation of the device at these or any other conditions above those indicated in the

operational section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

MAXIMUM POWER DISSIPATION

The 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

operation will be restored as soon as the die temperature is

reduced. Leaving the device in the “overheated” condition for

an extended period can result in device burnout. To ensure

proper operation, it is important to observe the derating curves

shown in Figure 24.

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.
