There are provided an analog-digital converter circuit capable of performing the same degree of operation as being performed at a high-frequency oscillation pulse using a low-frequency oscillation pulse without using the high-frequency oscillation pulse, a timing signal generating circuit generating a timing signal at the high frequency, and a control device using the circuits. In an analog-digital converter circuit, a periodic signal generating circuit allows the first to j-th pulse counting devices of the N pulse counting devices to count a count value X and allows the other pulse counting devices to count a count value X-1 in each sampling period by sequentially generating N serial periodic signals at a delay time interval of [approximate value of one period (T) of periodic signals]/N. A digital signal generating circuit converts the analog signal to the digital signal.
