Frequently Asked Questions (FAQs)
1. What does a comparator do to a signal?
A comparator compares two input voltages and outputs a binary signal indicating which is larger. It determines if the non-inverting input is greater than the inverting input, and if so, the output goes high.
2. What are the different types of voltage comparators?
There are two types of comparators: inverting and non-inverting. Inverting comparators and non-inverting comparators function differently and have distinct characteristics.
3. What is the difference between a comparator and an op amp?
Comparators are faster than op amps when it comes to comparing and responding to voltage levels. While op amps may miss narrow pulses, comparators can detect even the narrowest pulses.
4. Why do we need comparators?
Comparators provide flexibility and control over sorting behavior, making them useful for sorting objects based on different criteria or when objects do not implement the Comparable interface.
5. What are the benefits of a comparator?
Mechanical optical comparators offer advantages like not requiring an external power supply and providing high magnification capabilities for accurate measurements.
6. How does LM393 work?
The LM393 IC has two internally connected op-amps. These op-amps function independently, with one providing its own output. However, in some circuits, only one operational amplifier is used while the other remains unconnected.
7. Why is LM358 used as a comparator?
LM358 is commonly used as a voltage comparator in control systems. Its output goes high when the voltage at the non-inverting input is greater than the voltage at the inverting input.
8. Why not use an op-amp as a comparator?
Op amps may not be ideal as comparators due to higher power consumption compared to dedicated comparators. Additionally, the presence of input clamping diodes in some op amps may limit the allowable differential input voltage.
