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.
