Tagged: ADC0 - Constant polarization
Dear All,
My name is Marcin.
I noticed the following problem on my custom board.
Constant polarization above 1.8V (ADC0 = 4093). When I connect resistor 5k6 to GND, ADC0 shows 0.36V (ADC0 = 820).
I tested it on 2 copies of this version of the processor.
I also tested on a PCB made by another contractor – the same polarization.
SiP on Pocketbeagle – works well.
Please find attached detailed data of processors.
For clarity and asking questions in this regard.
I cut off all signal paths or polarity to the ADC0 input
Hi Marcin,
We have followed up on this issue offline. Please look out for a schematic review providing input on the issue from our sales team.
Best,
Neeraj
