AD5522 Absolute Maximum Ratings Parameter Rating Supply Voltage AVDD to AVSS 34V AVDD to AGND -0.3V to 34V AVSS to AGND 0.3V to -34V VREF to AGND -0.3 V, +7V DUTGND, REFGND, AGND AVDD +0.3V to AVSS -0.3V DVCC to DGND - 0.3V to 7V Digital Inputs to DGND - 0.3V to DVCC +0.3V Analog Inputs to AGND AVSS - 0.3V to AVDD +0.3V Storage Temperature –65°C to +125°C Operating Junction Temperature +25 to +90°C Reflow Soldering Peak Temperature 230°C Time at Peak Temperature 10s to 40s Junction Temperature 150°C max Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other condition s 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. THERMAL RESISTANCE3 Thermal resistance values are specified for the worst-case conditions, i.e., specified for device soldered in circuit board for surface mount packages. Table 4.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product 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. |
