The deviation of an actual code transition point from its ideal position on a straight line drawn between the end points of the transfer function. Integral nonlinearity (INL), expressed in terms of LSB In an ideal converter, every code is exactly the same size and DNL is zero.ĭNL, INL, offset error, and gain error specify how accurately the data represents the signal across the entire internal and external range. The deviation from the ideal (1 LSB) code width between any two adjacent codes. LSB size is a function of converter resolution.ĭifferential nonlinearity (DNL), expressed in terms of LSB
The right-most bit in an ADC output code.
The number of repetitive conversions per second for a full-scale change to specified resolution and linearityĭetermines the fastest sampling capability of the ADC Number of bits representing an analog signal, generally ranging from 6 to 24.ĭetermines how small an input can be resolved.Ĭonversion speed or rate, ksamples/s or Msamples/s Specification and terms, units of measure
