Spring is here...

Or it is supposed to be here in the UK. Maybe it's taking a holiday this year.

I am now moving again, so time to pack everything up. I had been looking at my DAC boards and trying to work out why the common mode voltage seems wrong. Or more specifically why it seems to be close to the tempreature sensor reference (TS_REF) voltage. The pins are labelled as per the datasheet, and the TS_REF output is at 0V which is also not normal with default registers.

I may get a little more time to play before I need to pack this stuff away, but ideally I need to build up a new board with just the DAC chip in place and work from here.
