Operational amplifiers and comparators are sometimes used interchangeably and, while they are different, an opamp can be setup as a comparator. Understanding how an opamp works, in a comparator configuration, can actually help you have a better intuitive understanding of how operational amplifiers truly operate. In this video tutorial, Josh reviews the comparator configuration, why you'd rather use a dedicated comparator if you can, and some of the pros and cons of using an operational amplifier instead.
