Using Op Amps as Comparators Characteristics Overview

WebUsing an Op Amp as a Comparator In general, if a given design calls for a comparator, it is best to simply use a comparator. Such a device is designed and optimized specifically … Web13 de dez. de 2024 · Op-amps can take some time to come out of saturation so this introduces a time delay. Many comparators have open-collector outputs so you can parallel them. This is useful in window-comparator applications. This means that when the inverting terminal voltage is greater, the load connected to output can be powered on. citric powder usesWeb13 de dez. de 2005 · Here is a question, sometime an op amp is used as a comparator, but most time a specific comparator is designed. So what is the disadvantage of using an op amp as a comparator? This is because normally opamp has compensation capacitor which will slow down response time of the output or the rising/ falling of the output. dickinson fine arts academy supply list
