Claims (1)

  1. 소정수의 저항기를 직렬로 접속시킨 분압회로(6)와, 이 분압회로의 각 분압점의 전압을 순차적으로 폐회로 스위치(8)를 경유하여 일괄적으로 입력을 하고, 아날로그 입력 전압을 다른쪽의 입력으로 하는 비교기(4)가 있으며, 스위치를 차례로 폐동작시켰을 때에 비교기(4)의 출력이 반전된 시점에서 폐회로 스위치에 대응하는 변환수치를 얻는 A/D변환기에 있어서, 분압회로의 적어도 한쪽에 저항기(26)와 스위칭소자(28)와의 병렬회로를 직렬로 접속하고, 이것을 정전압 직류 전원사이에 접속시켜서 된 것을 특징으로 하는 A/D변환기
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
