AD8421-KGDKnown Good DieABSOLUTE MAXIMUM RATINGS Table 2. Stresses at or above those listed under Absolute Maximum ParameterRating Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these Supply Voltage ±18 V or any other conditions above those indicated in the operational Output Short-Circuit Current Duration Indefinite section of this specification is not implied. Operation beyond Maximum Voltage at −IN or +IN1 −VS + 40 V the maximum operating conditions for extended periods may Minimum Voltage at −IN or +IN +VS − 40 V affect product reliability. Maximum Voltage at REF2 +VS + 0.3 V Minimum Voltage at REF −VS − 0.3 V Storage Temperature Range −65°C to +150°C ESD CAUTION Operating Temperature Range −40°C to +125°C Maximum Junction Temperature 150°C Electrostatic Discharge (ESD) Human Body Model 2 kV Charged Device Model 1.25 kV Machine Model 0.2 kV 1 For voltages beyond these limits, use input protection resistors. See the AD8421 data sheet for more information. 2 There are ESD protection diodes from the reference input to each supply. Therefore, REF cannot be driven beyond the supplies in the same way that +IN and −IN can. See the AD8421 data sheet for more information.
