Atmel ATtiny24/44/84 [Preliminary]
• Gain Error: After adjusting for offset, the gain error is found as the deviation of the last
transition (0x3FE to 0x3FF) compared to the ideal transition (at 1.5LSB below maximum).
Ideal value: 0LSB
Figure 18-10. Gain Error
• Integral Non-linearity (INL): After adjusting for offset and gain errors, the INL is the maximum
deviation of an actual transition compared to an ideal transition for any code. Ideal value:
0LSB.

• Differential Non-linearity (DNL): The maximum deviation of the actual code width (the interval
between two adjacent transitions) from the ideal code width (1LSB). Ideal value: 0LSB.
