analog-to-digital [A/D] converter (ADC)

A converter that uniquely represents all analog input values within a specified total input range by a limited number of digital output codes, each of which exclusively represents a fractional part of the total analog input range.

NOTE This quantization procedure introduces inherent errors of ±½ LSB (least significant bit) in the representation because, within this fractional range, only one analog value can be represented free of error by a single digital output code.
