ABSTRACT:
An integrated A/D converter includes an integrator 8integrating reference signals in synchronism with an integration start signal, and counters for counting integrating clock pulses until the integrated value of the integrator reaches a value corresponding to an input signal, thereby to convert the input signal into a digital or analog signal based on the counts of the counters. An AND gate supplies the integrating clock pulses to the counters only during a predetermined period in synchronism with the integration start signal, so that the integrating clock pulses are supplied to the counters only during an integrating period for the reference signals.
