What supplies the VADC pin on P9?

Is the VADC pin on P9 fed from the TPS65217C power controller - either
the VDD_1V8 rail or the VRTC rail? If it doesn't come from one of
these where does it come from?

It comes from the TPS65217C. Just check the schematic.

Ah, yes, thanks. Now it makes some sense to me having seen that the
VDDA_ADC and VREFP on the processor as well as the P9 pin.

Those schematics are hard work for my aging eyes though, even on a big
1600 x 1200 screen! :slight_smile:

PDF works great. Just search on the signal name and use the zoom function.
