Part Number: MSP430F6749A
Tool/software:
HI,
I'm using the 24Bit sigma delta ADC peripheral on MSP430,
I'm using the internal reference (measured at 1.159V).
The OVR is 256 (default) ,
Right aligned
Data format is binary (as appose to 2s compliment).
The ADC is used as single ended so the negative terminal is connected to 0V
The problem I have that when I input a voltage of 1.2V into one of the ADC's channel I don't get the full scale output, I only get it (i.e 0xFF FFFF) when I input a voltage of about 1.6V! so the ADC only saturates at input voltage way beyond the reference voltage.
