Table 109. Typical ADC input configurations
1. The differential is only in LV mode.
Input range
ADC inputs can be routed through input buffers to expand the input voltage range. The input
buffers have a fixed 0.25 gain and the converted data is scaled by that factor.
With the input buffers disabled the single-ended input range is 0 to VREF and the differential
input range is -VREF to +VREF. With the input buffers enabled the single-ended range is 0
to VDD_PADS and the differential range is -VDD_PADS to +VDD_PADS.
The input buffers are enabled for the ADC P and N inputs by setting the ADC_HVSELP and
ADC_HVSELN bits respectively, in the ADC_CFG register. The ADC accuracy is reduced
when the input buffer is selected.
