AD8657/AD8659Data SheetABSOLUTE MAXIMUM RATINGSTHERMAL RESISTANCETable 5. ParameterRating θJA is specified for the worst-case conditions, that is, a device Supply Voltage 20.5 V soldered in a circuit board for surface-mount packages using a Input Voltage (V−) − 300 mV to (V+) + 300 mV standard 4-layer JEDEC board. The exposed pad (LFCSP Input Current1 ±10 mA packages only) is soldered to the board. Differential Input Voltage ±VSY Table 6.

Limit the input current to 10 mA or less whenever input signals exceed the power supply rail by 0.3 V. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev.
