PROBLEM TO BE SOLVED: To furthermore suppress occurrence of a distortion of an analog output signal due to an on resistance value of a switch.SOLUTION: A feedback switch section 240 comprises a plurality of complementary MOS transistors connectable between one end of a sampling capacitive element section 250 and an output terminal of an operational amplification section 12. A clock generation section 11 supplies a first clock transitioning between a first high voltage level and a first low voltage level lower than the first high voltage level to gate terminals of first MOS transistors, and supplies a second clock transitioning between a second high voltage level and a second low voltage level lower than the second high voltage level to gate terminals of second MOS transistors other than the first MOS transistors. The feedback switch section 240 can adjust the first high voltage level and the second low voltage level. |
