... Range Description AD724JR +70 C 16-Lead SOIC AD724JR-REEL +70 C 16-Lead SOIC AD724JR-REEL7 +70 C 16-Lead SOIC AD724-EB Evaluation Board 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 AD724 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges ...
