LM293 Description

LM293 is a dual independent accurate voltage comparator.

LM293 has a capability to perform its operation from a single supply source as well as from split power supply.

The purpose to design LM293 is to permit a common mode range to the ground level and it perform this operation with single power supply source.

LM293 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.

LM293 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.

LM293 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. It is a low cost device and is easily available in the market now a days.
