Refers to common-mode transients across the insulation barrier. Common-

mode transients exceeding the absolute maximum ratings may cause latch-up

or permanent damage.

Analog Devices recommends that reflow profiles used in soldering RoHS

compliant parts conform to JEDEC J-STD 20. For the latest revision of this

standard, refer to JEDEC.

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

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

THERMAL RESISTANCE

θJA and θJC are specified for the worst-case conditions, that is, a

device soldered in a circuit board for surface-mount packages.
