LM393 is an integrated circuit having two builtin operational amplifiers which are frequency compensated internally. They are specially developed to perform different tasks using a single power supply sources. Moreover, they can also be operated using split power supply sources. small current drain supply, low input offset voltage, low input bias current are its major features. It can be used in time delay generators, battery powered systems, analog to digital converters etc.
The LM393 is a Dual in package comparator IC, meaning the IC has two comparators inside a single 8-pin package.
LM 393 has a lot of features e.g. wide voltage supply ranges, a very small current drain supply, low input offset current, low input bias current, output voltage compatible with Transistor Transistor Logic.
LM-393 has two internal operational amplifiers.
These are internally frequency compensated.
These are specifically designed to perform their tasks using a single power supply sources.
LM-393 can also perform its operations properly by using split power supply.
The current drain supply does not depend upon the magnitude of the power supply.
One of the most amazing feature of LM 393 is that ground is included in its common mode input voltage.
Its applications include industrial applications, battery powered systems, analog to digital converters, limit comparators, time delay generators etc.
