<P>PROBLEM TO BE SOLVED: To provide a pipeline type A/D converter capable of operating with a high precision, without increase in power consumption. Ž<P>SOLUTION: The analog to digital converter is configured with a plurality of stages. The plurality of stages include: CAP 307a, 307b, 307c, 307d, SW 304c, 304d, 304a, 304k, 304l, and 304i for separately sampling analog differential input signals VPin and VNin; SW 304c, 304d, 304k, 304l for determining a sampling operation timing for a sampling circuit, multiple value output circuits 306, 309 for adjusting the value of the sampled signals VPin and VNin according to the value of a digital signal dj; an amplifier 305 for holding the adjusted signals VPin and VNin; SW 304b, 304j for transferring analog differential output signals VPout and VNout; and an SW 304q for short-circuiting and equalizing a terminal 310 and a terminal 311 prior to transfer.
