<strong>ATmega32A</strong>Figure 22-10. Offset ErrorOutput CodeIdeal ADCActual ADCOffsetErrorV REFInput Voltage• Gain Error: After adjusting for offset, the Gain Error is found as the deviation of the lasttransition (0x3FE to 0x3FF) compared to the ideal transition (at 1.5 LSB below maximum).Ideal value: 0 LSBFigure 22-11. Gain ErrorOutput CodeGainErrorIdeal ADCActual ADCV REFInput Voltage• Integral Non-linearity (INL): After adjusting for offset and gain error, the INL is the maximumdeviation of an actual transition compared to an ideal transition for any code. Ideal value: 0LSB.8155C–AVR–02/11220
INL<strong>ATmega32A</strong>Figure 22-12. Integral Non-linearity (INL)Output CodeIdeal ADCActual ADCV REFInput Voltage• Differential Non-linearity (DNL): The maximum deviation of the actual code width (the intervalbetween two adjacent transitions) from the ideal code width (1 LSB). Ideal value: 0 LSB.Figure 22-13. Differential Non-linearity (DNL)Output Code0x3FF1 LSB0x000DNL0 V REF Input Voltage• Quantization Error: Due to the quantization of the input voltage into a finite number of codes,a range of input voltages (1 LSB wide) will code to the same value. Always ±0.5 LSB.• Absolute Accuracy: The maximum deviation of an actual (unadjusted) transition compared toan ideal transition for any code. This is the compound effect of Offset, Gain Error, DifferentialError, Non-linearity, and Quantization Error. Ideal value: ±0.5 LSB.8155C–AVR–02/11221
