Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

Maximum Power Dissipation

The maximum safe power dissipation for the ADA4853-1/

ADA4853-2/ADA4853-3 is limited by the associated rise in

which is the glass transition temperature, the plastic changes its

properties. Even temporarily exceeding this temperature limit

can change the stresses that the package exerts on the die,

permanently shifting the parametric performance of the

amplifiers. Exceeding a junction temperature of 150°C for an

extended period can result in changes in silicon devices,

potentially causing degradation or loss of functionality.

resistor load is the total power consumed from the supply

minus the load power.
