![]() If it goes below it, we can make the circuit performĪ different action. If it goes above it, then we can make the circuit perform a certain action. If we have a reference voltage (set at some value), and we have a variable voltage, using a comparator, we can tell whether the variable voltage goes above This is usually from some type of sensor such as to measure light, heat, fluids, etc. And usually the other voltage is unknownĪnd variable. Usually, a comparator will have one input that has a set (and known voltage). In this way, you can see how a comparator is used to check voltage levels. Op amp will be low (it will be whatever voltage is supplied to the V- terminal). If the voltage goes below 5 volts, then the output of the Of the LM741 will be high (it will be whatever voltage is supplied to the V+ terminal of the op amp). If it goes above 5 volts, then the output LM741 is 5V and the other is a voltage divider circuit, we can tell whether the other voltage goes below or above the 5 volts. Make decisions based on which input has larger voltage.Ĭomparators are very useful for many different types of electronic circuits.įor example, say that we are using the LM741 op amp as a comparator and we have 2 inputs we are monitoring. We will go over how the LM741 operational amplifier IC can be used as a comparator.Ī comparator is an electronic device that can compare voltages that are on its inputs to determine which is larger or which is smaller. Need help?Ĭontact us at for questions related to refunds and returns.How to Use the LM741 Op Amp as a Comparator We don’t guarantee that we will receive your returned item.
