This is a stress rating only and functional operation of the device at these or any other conditions above those listed in the operational sections of this spec- ification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. PIN 1 IDENTIFIER 1 2 3 4 5 Pin Configuration 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 AD22157 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. NC NC NC Vlow Vhigh PRELIMINARY TECHNICAL DATA |
