Data Sheet AD7414/ AD7415 ABSOLUTE MAXIMUM RATINGS Table 2.
Stresses at or above those listed under Absolute Maximum
Parameter Rating
Ratings may cause permanent damage to the product. This is a VDD to GND −0.3 V to +7 V stress rating only; functional operation of the product at these SDA Input Voltage to GND −0.3 V to +7 V or any other conditions above those indicated in the operational SDA Output Voltage to GND −0.3 V to +7 V section of this specification is not implied. Operation beyond SCL Input Voltage to GND −0.3 V to +7 V the maximum operating conditions for extended periods may ALERT Output Voltage to GND −0.3 V to +7 V affect product reliability. Operating Temperature Range −40°C to +125°C
