Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to LM293 an Integrated Circuit (IC). LM-293 is a dual independent accurate voltage comparator. LM 293 has a capability to perform its operation from a single supply source as well as from split power supply. The purpose to design LM-293 is to permit a common mode range to the ground level and it perform this operation with single power supply source. LM-293 is the most common device in the market these days due to its high performance and cost effectiveness. This device is considered to be an ideal for a lot of electronics applications. LM-293 has a lot of features which make it different from all other devices. These features include low input offset voltage, low input offset current, low input bias current, wide voltage supply ranges, power supply equal to differential input voltage ranges, lead (Pb) free and lot more. LM-293 can be used at several different places in real life. It can be used in gas sensors, chemical sensors, weigh scales, AC induction, personal computers etc. The further details about LM-293 will be given later in this tutorial.
