ADC accuracy definitions
Figure 24-9. ADC power connections.
An n-bit single-ended ADC converts a voltage linearly between GND and V
(LSBs). The lowest code is read as 0, and the highest code is read as 2
Several parameters describe the deviation from the ideal behavior:
• Offset: The deviation of the first transition (0x000 to 0x001) compared to the ideal transition (at
0.5LSB). Ideal value: 0LSB
and ADC5) will only affect the conversion on ADC4 and ADC5 and not the other ADC
channels.
