I thought that the AI-64 ADC was 1.8V as the Beaglebone Black so I was going to use an ADC converter on the SPI port. As I look into the specs it seems to be 3.3V.
I have to read voltage on a 24V system (0-32, 32V max when alternator not functionning right)
I’ve used 5V and 3.3V systems over the years for military and commercial vehicles, not sure the signal range would be acceptable at 1.8V
What is confusing is this : VDD_ADC_1V8_3V3
What is the purpose of this connection?
