6.6.1 ADC electrical specifications
The 16-bit accuracy specifications listed in Table 22 and Table 23 are achievable on the
differential pins (ADCx_DP0, ADCx_DM0, ADC, ADCx_DP1, ADCx_DM1,
ADCx_DP3, and ADCx_DP3). The ADCx_DP2 and ADCx_DM2 ADC inputs are used
as the PGA inputs and are not direct device pins. Accuracy specifications for these pins
are defined in Table 24 and Table 25. All other ADC channels meet the 13-bit
differential/12-bit single-ended accuracy specifications.
