# ADUM7640 - DC Isolation Spec

The ADUM7640 isolation spec is listed as 1000Vrms. Just want to verify that this translates to 1400VDC. The DC isolation spec we have to meet is 1KVDC..

• Hi Johnnyp,
This family of isolators will have the same rating for DC isolation as the AC isolation.

Thus, 1000VDC applies for a 1 minute test and 1200VDC for a 1 second test with a current leakage detection limit set to 5uA.
