Hello readers welcome to the new post. In this post, we will learn Differences Between OP-AMP and Comparator. These 2 devices are the part of differential amplifier family and there are common features are inputs and output terminals. There are symbolic representation is also same. If we do a comparison between them come to know that there is an open circuit collector at the comparator and at the operational amplifier there is NPN and PNP configuration.
Here we discuss their different parameters and finds their common differences. So let get started.
Differences Between Operational Amplifier and Comparator
What is Operational Amplifier
- The operational amplifier is an amplifier having a large gain coupled to DC also comes with differential inputs means positive and negative.
- There is a single input terminal it has. Its output volts have a one lac time larger value than the inputs volts.
- There is linear, arithmetic, and nonlinear functions in the analog computer are done by this module.
- Its versatile nature makes it useful in analog modules.
- It has two main types first one is the inverting and the second one is non-inverting operational amplifier.
- The output, gain value input, and value of output impedance can be measured through use of the negative feedback function.
- It is employed at industry, electronic modules, and different instruments used in the laboratory.
- Its prices are very less but some hybrid OP amp has a larger cost due to some extra features.
Introduction to Inverting Amplifier
- his category of the amplifier provides the output at an angle of one-eight degrees than input. IF a positive value of supply is provided to this circuitry output of the circuitry will be negative.
- There are one-eighty degrees of phase difference between input and output.
- Input is given at the non-inverting terminal or negative of circuitry.
- Its polarity is more negative than another amplifier.
- It’s gaining the ratio of resistance at output and input.
What is a Non-Inverting Amplifier
- The output of this amplifier is in phase with the input given at this circuitry.
- Its gain polarity is positive.
- Gin is the sum of one and the ratio of resistance
- There is zero phase difference between input and output.
- Its input is given at the positive terminal of the circuitry.
- Its output has a noninverted behavior than the inverting amplifier.
What is Comparator
- It is such a device that generates the output after making the comparison between the applied voltage at 2 terminals.
- The output at the terminals indicates which input has a high value or less.
- It has 2 input terminals and a single output where the comparison of 2 inputs is given.
- It main types are listed here.
- Mechanical Comparator
- Electrical-Electronic Comparator
- Pneumatic Comparator
- Mechanical-Optical Comparator
- Reed Type Comparator
What are the basics of operational amplifiers and comparators?
- The fundamental work of operational amplifiers is to amplify the differential between two inputs voltatge and output provided. If the input for V+ is higher as compared to V- output will be high and if V- is higher than operational amplifiers output will be a negative signal
Why is it called op-amp?
- The operational amplifier is an integrated circuit that amplifies the difference of inputs. It is called since it is made for performing arithmetic operations.
What is the use of a comparator?
- The comparator circuit makes a comparsion between two voltage and outputs one or zero for a larger value. A comparator is used to check the input to reach a predetermined value.
What are the limitations of op-amp as comparator?
- The power use of mostly operational amplifiers will be larger as compared to the equivalent comparator. The differential input voltage can restricted with the existence of input clamping diodes, based on the op-amp circuit.
What is CMRR and slew rate?
- The CMRR of operational amplifiers is the ratio of differential voltage gain with common mode voltage gain. A slew rate is a high rate over output voltage that can distorted.
What is the application of comparator?
- The uses are converting analog signals into make best for frequency measurement values or controlling power electronics circuits that should switch for relation of AC signal
