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
chip can also drive over 800V between High-side and Low-side, or how much
voltage it can drive?


The output channels of ADuM3220 share the same GND so if your application
requires isolation between the two outputs then ADuM3220 does not fit. Please
find a short summary attached.
