ABSTRACT:
A DA converter has an N-bit binary counter which counts pulses of a predetermined frequency to generate a plurality of binary numbers within one conversion period. The binary counter supplies an output of lower n significant bits (n-1<N) to the upper (N-n+1)th to Nth bits of a comparator, and inverts an output of the upper (N-n) bits in order and supplies the inverted signal to the least significant bit to the (N-n)th bit of the comparator. The comparator sequentially compares digital data to be converted with the binary number output from the binary counter. The comparator then supplies the comparison results, pulses, to a low-pass filter. The low-pass filter converts a pulse train output by the comparator into a dc output.
