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 …
