I am currently doing a schematic using the ADUCM4050, and his internal ADC, and I would like to know few stuff :
- Is that possible to have Vbat_ADC set to a different value than the other Vbat of the microcontroller ?
- Is that mandatory to have Vbat_ADC = Vref_ADC ?
I am asking this cause I would like to powered up the ADUCM4050 with 2.5V, and having a Vref for the ADUCM40050 ADC's set to 3.3V (cause we would like to measure voltage up to 3V approximatively).
So is that possible to set :
Vref_ADC = 3.3V // Vbat_ADC=3.3V // other Vbat=2.5V
Vref_ADC = 3.3V // Vbat_ADC=2.5V // other Vbat=2.5V
Thanks for your help,
