Data Sheet AD7328 ABSOLUTE MAXIMUM RATINGS
TA = 25°C, unless otherwise noted
Table 4. Parameter Rating
Stresses above those listed under Absolute Maximum Ratings V may cause permanent damage to the device. This is a stress DD to AGND, DGND −0.3 V to +16.5 V V rating only; functional operation of the device at these or any SS to AGND, DGND +0.3 V to −16.5 V V other conditions above those indicated in the operational DD to VCC VCC − 0.3 V to +16.5 V V section of this specification is not implied. Exposure to absolute CC to AGND, DGND −0.3 V to +7 V V maximum rating conditions for extended periods may affect DRIVE to AGND, DGND −0.3 V to +7 V AGND to DGND −0.3 V to +0.3 V device reliability. Analog Input Voltage to AGND1 V SS − 0.3 V to VDD + 0.3 V Digital Input Voltage to DGND −0.3 V to +7 V
