17.10 ADC Accuracy Definitions
8008G–AVR–04/11
Where high ADC accuracy is required it is recommended to use ADC Noise Reduction Mode, as
described in
is above 1 MHz, or when the ADC is used for reading the internal temperature sensor, as
described in
bypass capacitors does reduce the need for using ADC Noise Reduction Mode
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:
Figure 17-10. Offset Error
• Offset: The deviation of the first transition (0x000 to 0x001) compared to the ideal transition
(at 0.5 LSB). Ideal value: 0 LSB.
