Part Number: TMS320F280025
I am using 280025. ADC Moudle is configured
Internal reference mode
Internal 1.65V reference mode (3.3V reference range)
The formulas of conversion results is
ADCRESULTx = 4096(ADCINy - VREFLO)/(VREFHI - VREFLO)
My question is
VREFHI - VREFLO = ? (1.65V or 3.3V)
According to the Reference Manual(spruin7a) and datasheet, in internal 1.65V reference mode, VREFHI should be 1.65V, then VREFHI - VREFLO =1.65V. But the experimental results are wrong according to the above assumption.
Please help me to confirm the problem, thank you!
