If the Common-Mode Input Voltage Range −VS − 0.5 V to +VS + 0.5 V rms signal levels are indeterminate, consider the worst-case Differential Input Voltage ±VS scenario, when VOUT = VS/4 for RL to midsupply.

More stress rating only; functional operation of the product at these metal directly in contact with the package leads and exposed or any other conditions above those indicated in the operational paddle from metal traces, throughholes, ground, and power section of this specification is not implied. Operation beyond planes also reduces θJA. the maximum operating conditions for extended periods may affect product reliability.

extended period can result in changes in silicon devices, potentially causing degradation or loss of functionality. The power dissipated in the package (PD) is the sum of the quiescent power dissipation and the power dissipated in the die due to the ADA4817-1/ADA4817-2 drive at the output. The quiescent power is the voltage between the supply pins (VS) multiplied by the quiescent current (IS). PD = Quiescent Power + (Total Drive Power – Load Power) (1) Rev.
