ABSTRACT:
A parallel comparison type A/D converter comprises a voltage divider having 2.sup.N divider junctions connected in series between a reference voltage terminal and a ground potential terminal, 2.sup.N comparators for receiving as reference voltages the outputs of the respective divider junctions, a position detection logic circuit for receiving the outputs of the comparators, an encoder for receiving the output of the position detection logic circuit, and a code converter for receiving the output of the first digital encoder. The encoder adopts the Gray code format, and the code converter converts the Gray code format into the binary code format.
