8.4.2 Differential non-linearity error
The differential non-linearity error indicates the difference between the 1 LSB step width (the ideal analog
input voltage width while the same output code is expected to output) of an A-D converter with ideal
characteristics and the actual measured step width (the actual analog input voltage width while the same
output code is output). For example, when V
characteristics is 20 mV, however when the differential non-linearity error is ±1 LSB, the actual measured
1 LSB width is 0 to 40 mV. (Refer to section “16.1.3 A-D converter standard characteristics.”)
