Further detail about the particular IC will be given later in this tutorial. It has a lot of real life applications e.g. basic comparator, driving CMOS, driving TTL, low frequency op-amp, Transducer amplifier etc. First of all, it compares the 2 different inputs applied at the input terminal and then gives the output in digital form in order to indicate which of the input applied has a larger amplitude. A comparator rotates a signal between digital and analog domain. LM 339 is a comparator IC having 4 builtin comparators. ![]() At its input terminal, it compares the two different input voltages applied, gives digital output and indicates the larger input applied at the input terminal. The basic purpose of a comparator is to rotate the signal between analog and digital domains. ![]() There is a unique characteristic of comparators, Input Common-Mode Voltage Range (I CMR) includes a ground even when it is operating from a single power supply voltage.īasically, LM339 is a comparator IC having four built-in comparators. It can also operate for split power supplies. Each comparator is designed in such a way that it is capable of operating from a single power source over a wide range of power supplies. LM339 belongs to the family of devices having 4 independent voltage comparators. Today, I am going to share my knowledge about Introduction to LM339. ![]() Hello everyone! I hope you all will be absolutely fine and having fun.
