Data Sheet AD8232 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 stress rating only; functional operation of the product at these Supply Voltage 3.6 V or any other conditions above those indicated in the Output Short-Circuit Current Duration Indefinite operational section of this specification is not implied. Maximum Voltage, Any Terminal1 +VS + 0.3 V Operation beyond the maximum operating conditions for Minimum Voltage, Any Terminal1 −0.3 V extended periods may affect product reliability. Storage Temperature Range −65°C to +125°C Operating Temperature Range
