NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device.This is a stress rating only; functional 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.
28-Lead Plastic Package: JA = 100°C/W; JC = 50°C/W. 8-Lead SOIC Package: JA = 155°C/W; JC = 40°C/W.

METALLIZATION PHOTOGRAPH
Dimensions shown in inches and (mm).
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 AD626 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.
