Under the scenario of comparing the analog signals, the integrated analog comparator is a cost effective scheme to replace an operational amplifier. But unlike the continuous comparing of the operational amplifier, ESP analog comparator is driven by a source clock, which decides the sampling frequency.
Analog comparator on {IDF_TARGET_NAME} has {IDF_TARGET_SOC_ANA_CMPR_NUM} unit(s), the channels in the unit(s) are:
