11.7.4 Data Conversion Value Equations
Use the following equations to calculate the ADC data value for a conversion for the selected channel. If using the internal
reference, V
REF
= 1.22V; otherwise V
REF
= VDDA.
Equation 11-4: ADC Data Calculation for Input Signal ADC_CTRL.adc_ch_sel = 0x00 thru 0x07 (AIN0 – AIN7)
Note: Must satisfy Equation 11-3.
Equation 11-5: ADC Data Equation for Input Signal ADC_CTRL.adc_ch_sel = 0x08 thru 0x0C (V
