AD7902 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 5.
Stresses at or above those listed under Absolute Maximum
Parameter Rating
Ratings may cause permanent damage to the product. This is a Analog Inputs stress rating only; functional operation of the product at these INx+, INx− to GND1 −0.3 V to V + 0.3 V or ±10 mA or any other conditions above those indicated in the operational REF Supply Voltage section of this specification is not implied. Operation beyond REFx, VIOx to GND −0.3 V to +6.0 V the maximum operating conditions for extended periods may VDDx to GND −0.3 V to +3.0 V affect product reliability. VDDx to VIOx +3 V to −6 V
ESD CAUTION
Digital Inputs to GND −0.3 V to V + 0.3 V IO Digital Outputs to GND −0.3 V to V + 0.3 V IO Storage Temperature Range −65°C to +150°C Junction Temperature 150°C Lead Temperatures Vapor Phase (60 sec) 255°C Infrared (15 sec) 260°C 1 See the Analog Inputs section for an explanation of INx+ and INx−.
