1 Sustained operation above 125°C results in a shorter product lifetime. For
more information, contact Analog Devices.
2 Values relate to package being used on a standard 2-layer PCB. This gives a
worst-case θJA and θJC.
3 TA = ambient temperature.
4 Junction-to-case resistance is applicable to components featuring a
preferential flow direction, for example, components mounted on a heat
sink. Junction-to-ambient is more useful for air-cooled, PCB-mounted
components.
Data Sheet
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.
