I am working on MM912J637 iBS. How can i change Vref for the inbuilt adc ? I am not able to find a specific vref setting in the datasheet. Can someone please suggest a solution?
looking at the datasheet it seems like it is not possible to change Vref.
In the Current and Voltage Measurement (section 4.8.3), there is described Gain Control Block (GCB). It mentions Vref in the Table 99., but this is related to PGA and not the ADC.
It looks like ADC reference voltage is fixed.
