Webb28 mars 2012 · Fig. 3 THD vs. Input Frequency for a 16-bit, 40kHz Sampling ADC. The INL specification for this device applies only with low frequency inputs, the very left hand side of the graph. As the frequency of the input signal increases, the output codes will deviate more and more from the desired ideal output code, and the INL worsens. WebbDifferential non-linearity is a measure of the worst-case deviation from the ideal 1 LSB step. For example, a DAC with a 1.5 LSB output change for a 1 LSB digital code change exhibits 1⁄2 LSB differential non-linearity. Differential non-linearity may be expressed in fractional bits or as a percentage of full scale.
