From the sample circuit below, we can see a high output voltage when pin7 has a lesser voltage than pin2.Then, pin4 remains grounded to keep the circuit at 0V potential. Here, pin8 (voltage supply pin) connects to +5V supply voltage.Let’s use an example where by the IC LM393 receives a +5V supply voltage circuit. Storage temperature – -65☌/W to 150☌/W,.The features of LM393 IC have the following parameters and values So, the table below will further explain its pinout and the functions of each pin in the 8-pin package. Additionally, they can also apply a split power supply in their working, and it’s a dual package comparator IC.Īn IC LM393 comparator has a total of two independent voltage comparators in its single 8-pin package. LM393 is an integrated circuit with two internally inbuilt operational amplifiers that use a single power supply to perform different tasks. There are a variety of comparators, such as LM311, LM393, etc., but we’ll focus on the latter. Generally, the comparators are miniature voltmeters that have switches. A voltage comparator is an electronic component that compares two currents or voltages, then determines which is greater at the output.
