LM393 – Dual Comparator

LM393 is a widely used voltage comparator IC available in 8 Pin Dip, SO-8 and other packages. This small IC is packed with many good features that make it ideal IC to use as a comparator. The IC contains two separate high accuracy comparator opamps that can be operated from single or dual power supply. One good feature is its wide supply voltage range that makes it possible to use this IC in wide variety of applications. The IC also requires low operating current due to which it is ideal to use in portable and battery operated devices. The output drive logic systems therefore it can be used in digital circuits. On the other hand this IC is also widely used by electronic students, hobbyists and tinkerers in their project. The maximum output current of the IC is 20mA which his enough to drive transistors and logic systems, logic devices and microcontrollers.
