# What is the difference between the lm324n as a comparator and the lm339 comparator does the op amp version perform as expected?

## What is the difference between the lm324n as a comparator and the lm339 comparator does the op amp version perform as expected?

lm339 vs lm324 The only difference will be that you can connect its output to larger voltages then its supply because of the OC output stage. On the other hand, you can not replace 324 with 339 in linear applcations because 329 as comparator has only Low or High as the output stages..

### What is the difference between an amplifier and a comparator?

The basic difference between the comparator and the amplifier is that the amplifier amplifies the input signal or changes its amplitude level with minimum distortion of original signal but the job of comparator is to compare the two signals and give the indicationt so that we can know which signal has more strength.

Is a comparator and op amp?

Most comparators are quite fast and some are very fast indeed—but so are some op amps. A comparator is designed to be used with large differential input voltages, whereas op amps typically operate closed loop with their input voltages minimized by negative feedback.

Why are operational amplifiers considered the building blocks of analog and mixed signal systems?

Operational amplifiers are the main building block of analog systems. They can provide gain, buffering, filtering, mixing and multiple mathematic functions. In system diagrams, they are represented by a triangle with 5 connections: positive supply, negative supply, positive input, negative input and output (Figure 1).

## Can we use 2 LM311 instead of LM358?

We can use a LM358 single supply op-amp. Fortunately the LM339, LM393, and LM311 are all single supply comparators with open collector outputs. They all work the same: when the voltage on the Reference input is greater than the voltage input the output is switched ON or OFF.

### What is the difference between LM324 and LM339?

The LM324 has a complementary output while the LM339 is open collector. In the complementary output, current can flow in either direction as required (either source or sink) while the open collector output can only sink current.

What is comparator circuit?

A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.

What circuits use comparators?

Op-amp window comparators are a type of voltage comparator circuit which uses two op-amp comparators to produce a two-state output that indicates whether or not the input voltage is within a particular range or window of values by using two reference voltages. An upper reference voltage and a lower reference voltage.

## What is the difference between analog and digital IC?

Analog integrated circuits work on continuous varying (with respect to time) signals. They are used to construct electronic circuits such as amplifiers, voltage comparators, etc. Digital circuits are non-linear because they work on binary or discontinuous signals.

### Which voltage the op amp can amplify?

An operational amplifier is a very high gain voltage amplifier. It is used to amplify the signals by increasing its magnitude. Op-amps can amplify both DC and AC signals.

What is difference between LM358 and LM393?

The LM358 Op-Amp and the LM393 Comparator are two common jellybean components that are characterized by their ease of use and availability….Major Differences Between LM358 and LM393.

LM358 LM393
Output linear with input Non-linear output
Stable with negative feedback Stable with positive feedback

How does comparator get high rate of accuracy?

How to obtain high rate of accuracy in comparator? Explanation: High voltage gain causes comparator output voltage to switch between saturation levels. High CMRR rejects noise at input terminal and input offset (voltage & current) help to keep changes in temperature variation very slight.

## What is the output voltage of lm311?

LM311 is a dedicatedly designed high speed differential comparator responsible for comparing voltages. The operating supply voltage can range from -15 to +15V for OP-AMPs. This voltage is 5V if LM311 is to be used for logical operations. The compatibility of LM311 output with TTL and MOS circuits is quite good.

### How to use lm311 comparator?

LM311 is a single-channel comparator. When using it, connect the reference voltage and the compared signal voltage to its non-inverting and inverting input terminals (pin 2 and pin 3), and its output is the result of the comparison. If you want the foward output result, pin 7 is connected to the positive power supply and pin 1 is the output.

What is the lm311 differential comparison operational amplifier?

The lm311 differential comparison operational amplifier is a very old Ti comparison IC which has been used in voltage comparison with electronic design for a long time. Any operational amplifier can be used as a voltage comparator, but lm311 proves its advantage by placing an output transistor in its package.

What is the difference between lm311 and LM393?

LM311 has a load current of up to 50MA and a voltage of 40V. It can drive relays with a minimum power supply voltage of 5V. The LM393 load current is 16MA, and the minimum voltage is 2V for a single power supply. What’s the difference between LM311 and LM111? Their functions are the same, and the 1XX series can be used in harsher environments.
