LM393 Comparator Introduction

The LM393 IC can be considered as the equivalent comparator version of the most popular LM358 Op-Amp. While any Op-Amp can be made to work as a voltage comparator, the LM393 proves itself to be advantages by providing an open collector output making it suitable to drive loads.

The output transistor can drive loads upto 50V and 50mA which is suitable for driving most of the TTL, MOS and RTL loads.  The transistor can also make the Load to be isolated from the system ground. So if you are looking for a Voltage comparator to drive loads of these specifications then this IC might be the right choice for you.

Applications
  • Voltage Comparator circuits
  • Can drive Relay, Lamp, Motor Etc
  • Zero Crossing detector
  • Peak voltage Detector
  • High Voltage protection/Warning
  • Oscillator circuits
