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

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

or permanent damage.

2 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 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.

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.

1 Refers to the continuous voltage magnitude imposed across the isolation barrier. For more information, see the Insulation Lifetime section.

Note that greater working voltages than the values presented in Table 13 shorten the lifetime of the product (see Insulation Lifetime

section). Therefore, although some certifications in Table 7 state bigger maximum working voltages, use the ADE7933/ADE7932 only for

working voltages lower than the values presented in this table.
