ABSOLUTE MAXIMUM RATINGS
Ambient temperature = 25°C, unless otherwise noted.
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.

1 Does not apply to ADuM1400W, ADuM1401W, and ADuM1402W
automotive grade versions.
2 Applies to ADuM1400W, ADuM1401W, and ADuM1402W automotive grade
versions.
3 All voltages are relative to their respective ground.
4 VDDI and VDDO refer to the supply voltages on the input and output sides of a
given channel, respectively. See the PC Board Layout section.
5 See Figure 4 for maximum rated current values for various temperatures.
6 This refers to common-mode transients across the insulation barrier.
Common-mode transients exceeding the Absolute Maximum Ratings
may cause latch-up or permanent damage.

1 VIx and VOx refer to the input and output signals of a given channel (A, B, C, or D). VEx refers to the output enable signal on the same side as the VOx outputs. VDDI and
VDDO refer to the supply voltages on the input and output sides of the given channel, respectively.
2 In noisy environments, connecting VEx to an external logic high or low is recommended.
