Data SheetAD8232ABSOLUTE 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 3.6 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, Any Terminal1 +VS + 0.3 V the maximum operating conditions for extended periods may Minimum Voltage, Any Terminal1 −0.3 V affect product reliability. Storage Temperature Range −65°C to +125°C Operating Temperature Range −40°C to +85°C ESD CAUTION Maximum Junction Temperature 140°C θJA Thermal Impedance2 48°C/W θJC Thermal Impedance 4.4°C/W ESD Rating Human Body Model (HBM) 8 kV Charged Device Model (FICDM) 1.25 kV Machine Model (MM) 200 V 1 This level or the maximum specified supply voltage, whichever is the lesser, indicates the superior voltage limit for any terminal. If input voltages beyond the specified minimum or maximum voltages are expected, place resistors in series with the inputs to limit the current to less than 5 mA. 2 θJA is specified for a device in free air on a 4-layer JEDEC board.
