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.

Absolute maximum ratings apply individually only, not in

combination.

THERMAL OPERATING RANGES

The ADP1972 can be damaged when the junction temperature

limits are exceeded. The maximum operating junction

temperature does not guarantee that the junction temperature

In applications with high power dissipation and poor printed

circuit board (PCB) thermal resistance, the maximum ambient

temperature may need to be derated. In applications with

moderate power dissipation and low PCB thermal resistance,

the maximum ambient temperature can exceed the maximum

limit when the junction temperature is within specification

limits.

Use the following equation to calculate the maximum junction
