Digital controller of analog comparator

The invention discloses a digital controller of an analog comparator. The digital controller comprises an ACMP register set, a channel switching counter, a filtering counter, a polling channel counter and a positive and negative end output channel selection module. The four working modes of a single continuous mode, a single sequence mode, an intermittent sequence mode and a continuous sequence mode are achieved, channels for comparison are selected through the positive and negative end output channel selection module, the channel switching time can be freely controlled, and comparison results of all polling channels are updated in real time. Moreover, a new polling channel can be configured in the comparison process, and a user can flexibly define the comparison sequence of the channels. According to the technical scheme, various analog comparator working modes can be achieved, configuration is flexible, and the analog comparator is suitable for various working occasions and wide in application range. 本发明公开了
