Abstract: Also called code density test, the histogram test approach helps determine nonlinearity parameters such as differential and integral nonlinearities (INL and DNL) in data converters. The following application note lends insight into the mathematical relationship between probability density function and various data converter specifications required to successfully complete the histogram test
