Understanding the Definitions of INL and DNL in an ADC

Webb8 jan. 2024 · For an ideal ADC with uniform steps, the resolution determines the minimum change in the analog input voltage that makes the output change by one count. For example, an ADC with 12-bit resolution could resolve 1 part in 2 12 (1 part in 4096). In other words, a 12-bit ADC can detect voltages as small as 0.0244% of the full-scale value. WebbIntroduction. The dynamic performance of an analog-to-digital converter (ADC) is determined by the effective number of bits (ENOB).
