(VDD = +11.4 V to +15.75 V, VREF = +10 V, VPIN3 = VPIN4 = 0 V, VSS = 0 V or –300 mV. All specifications TMIN to TMAX unless otherwise noted. See Figure 1 for Timing Diagram.) WARNING! ESD SENSITIVE DEVICE 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 AD7538 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. Figure 1.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. |
