A Half-Gray digital encoding technique is disclosed for use in a parallel analog-to-digital converter (ADC) that reduces the ADC's output errors. A thermometer code, proportional to the ADC's analog input, is provided to a decoder which produces 2n output lines with one active line for each binary 0-to-1 transition in the thermometer code. A 1-of-(2n)-to-Half-Gray encoder converts the decoder output to a Half-gray code which has error reducing properties. The Half-Gray code is then provided to an n-bit Half-Gray-to-binary decoder for converting the Half-Gray code to a standard Binary code ADC output.
