PIN CONFIGURATION
20-Lead PLCC
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 AD831 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.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specication is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Thermal Characteristics:
20-Lead PLCC Package:
JA
= 110°C/W;
JC
= 20°C/W.
Note that the
JA
= 110°C/W value is for the package measured while suspended
in still air; mounted on a PC board, the typical value is
JA
= 90°C/W due to the
conduction provided by the AD831’s package being in contact with the board, which
serves as a heat sink.
