手册K60P144M120SF3.PDF上有这么一段描述:
6.6.1 ADC electrical specifications
The 16-bit accuracy specifications listed in Table 28 and Table 29 are achievable on the
differential pins ADCx_DP0, ADCx_DM0.
The ADCx_DP2 an DCx_DM2 ADC inputs are connected to the PGA outputs and are
not direct device pins. Accuracy specifications for these pins are defined in Table 30 and
Table 31.
All other ADC channels meet the 13-bit differential/12-bit single-ended accuracy
specifications.
我是不是可以这样理解:除了那个几个差分输入通道的ENOB理论上为16位外,其余单端输入通道的ENOB最大也就是12位?
