Abstract: Provided is an integrating analog-digital converter. According to the present examples, the resistance against external noise is improved by incorporating a differential amplifier into an integrating analog-digital converter. Some examples also include a section where an input voltage and a reference voltage are simultaneously blocked such that switching noise may be minimized and a reference voltage may also be stably supplied.
