8.3.12.1 ADC Divider Ratios

The ADC voltage inputs are each divided down to the full-scale input of 1.2 V. The ADC current sensing elements are not divided.

Table 8-1 shows the divider ratios for each ADC input. The table also shows which inputs are auto-sequenced in the round robin automatic readout mode.
