I'm prototyping a product including the ADuM5202 isolator IC. I'm seeing odd behaviour on the logic outputs VOA and VOB.
The rest of the observed voltages are as expected i.e. I'm feeding it with 3.3v, seeing just slightly above 3.3v on the Viso side, etc. but when either input VIA or VIB is high, the relevant output pin sits at about 0.93v. The output net is connected directly to an input pin on a microprocessor, there's no other load on it.
Am I missing something? Vcc is decoupled with 0.1uF and 10uF caps as per the datasheet.
