Any Op-Amp can be made to work as a voltage comparator, but the LM proves itself to be advantages by housing an Output Transistor inside its package. The simplified schematics of the IC is shown below:. 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. If the voltage at the Non-Inverting Terminal pin 2 is higher than the Inverting Terminal pin 2 , the output pin 7 will also be high else the output will be low.

This product has shipping restrictions, so it might have limited shipping options or cannot be shipped to the following countries:. Added to your shopping cart. The LM device is a single high-speed voltage comparator. It is capable of driving lamps or relays and switching voltages up to 50 V at 50 mA.
All inputs and outputs can be isolated from system ground. Offset balancing and strobe capabilities are available, and the outputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardless of the differential input.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics. Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that? See all skill levels.
