Abstract
A data conversion circuit has an input terminal for receiving serial data as time-divided multiple signals, a plurality of sample-and-hold circuits each connected to the input terminal, and output terminals each connected to an associated one of these sample-and-hold circuits to output the received signals as parallel data. At least one of these sample-and-hold circuits is formed with a first switch circuit which is connected on one side to the input terminal and is adapted to be switched on according to a first timing, a second switch circuit which is connected on one side to the input terminal and is adapted to be switched on according to a second timing different from the first timing, a first capacitor and a second capacitor connected respectively to the other side of the first and second switch circuits for holding received data, a third switch circuit having a common contact and being adapted to connect the common contact selectively either to the first capacitor or to the second capacitor according to a third timing different from the first timing and the second timing, and an amplifier connected between the common contact of the third switch circuit and the output terminal to output data from selected one of the capacitors.
