Abstract
PURPOSE:To prevent an analog input signal from being decreased, by setting the reference voltage of a comparator by the clamping voltage of the analog input signal at the time of turning ON a switch. CONSTITUTION:Plural comparators 121-12n-1 are provided with respect to the number of bits of a digital output signal. And the analog input signal from an input terminal 11 is supplied directly to the input sides on one sides of those comparators 121-12n-1, and also, the reference voltage obtained by plural division resistors 131-13n-1 connected in series is supplied to the input sides on the other sides of the comparators 121-12n-1. Also, a switch 6 ON/OFF- controlled with respect to the period of the analog input signal and a voltage buffer 15 are connected between the prescribed terminals of the division resistors 131-13n-1 and an analog input terminal, and a capacitor 17 is connected between the connection point of them and the ground. And the analog input signal at the time of turning ON the switch 16 is charged to the capacitor 17, and the clamping voltage is set as the reference voltage of the comparators 121-12n-1, In such a way, it is possible to prevent the analog input signal from being decreased.
