... 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 AD53508 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 ...

... F1, F2, F3, and F4. 2. The endpoints of the linearity curve are determined by –full scale (or LOW), and the +full scale (or HIGH) readings at the same FORCE pin current. 3. Using these endpoints, gain nonlinearity is computed and tested at the 1/4 scale, 1/2 scale, and 3/4 scale points. AD53508 FORCING VOLTAGE S6 DAC1 S7 ...
