We have used ADUM3223 to drive high Voltage output, but it needs two different supplies (15V). Your colleague at Embedded World 2014 recommended ADuM3220. But I didn’t find the work voltage of ADuM3320. Could you please tell me, if this
Adum3223 why is the output VOA VOB high when vdd1 = 5V and via VIB = 3.3V? In the specification, when vdd1 = 5V, via VIB needs to be greater than 0.7 * vdd1 = 0.7 * 5V = 3.5V, and the output above 3.5V is high level?
