What are ADC and DAC?

ADC stands for Analog to Digital Converter, which converts the analog signal into the digital signal.

DAC stands for Digital to Analog Converter and it converts the Digital signal into an analog signal.

ADC and DAC are an essential part of our life and by some or other way we are using in our day to day life.

Why we use ADC and DAC?

Most of the naturally occurring signals are analog in nature. The analog signals are susceptible to noise and difficult to store and process.

And the digital domain, it is easy to store and process these signals.

That's why for storage and processing signals are converted into digital form and it is retrieved using DAC.

Steps involved for the analog to digital conversion:

1. Sampling
2. Quantization
3. Encoding

In this video, each step is explained briefly and how the error is introduced during the process is also explained.

Important parameters for ADC and DAC

1. Resolution
2. Reference Voltage
3. Conversion and/or settling time
4. Gain and Offset Error
5. Non-linearity (Differential and Integral Non-linearity)
6. Accuracy
7. Total Harmonic Distortion (For DAC)

Types of ADC :

1. Flash ADC
2. Dual Slope ADC
3. Successive Approximation Type ADC (SAR)
4. Sigma-Delta ADC

Types of DAC:

1. Binary Weighted Resistor Type DAC
2. R-2R ladder Type DAC

This video will be helpful to everyone in understanding the basics of ADC and DAC (What is ADC and DAC, How it Works and Important Parameters of ADC and DAC).

Saviour of my exam hell yeah thank you man ❤️ knowing or unknown ur helping us a lot in mechatronics.

[benmaynard]

you spent a lot of time editing that, and it paid off well . good video

[davidpribic]

Well done, this is probably the best video about the ADC/DACs on the internet. Keep it going.

[viveknepal]

Thank you so much for sharing awesome knowledge in the simplest way

[subamaa]

My last semester syllabus is full of this ADC & DAC concept....I feel like if this video uploaded a little before...I would have preferred a little better for the exams...but thank u so much for uploading this video...now I understand more about converters...tq sir...👍

[derivaldosilvadossantos]

Hi Guy, your all videos are very good. I'm glad about it. Thanks man.. keep Continue with this !!!!

[nassional]

Refined information, beautiful and fluent explanation. Thanks

[sanjayshah]

Really love your videos and waiting for the new ones 👍👍

[nthumara]

thank youuu sir i wach them over and over again thank to you i am a yhe best student in my electronic class

[nethmimaduhansi]

Really informative.. Thank you so much ♥️

[dhruvamj]

Your explanation is very good ☺️ I can easily understand tqu

[ganeshgm]

Thanks heart of presents in the channel..

[nthumara]

thank youuuu sir this is really helpful for my electronic class

[blak]

It took me 12 hrs to understand this, , I've gone through so many sites.

[kumarsamyak]

can we use any other device in place of ADCs and DACs for converting analog signal to digital signal and as well as from digital to analog signal?

[LifewithKhandelwal]

Hello,


Can your videos be used for sharing for academic purposes?

[dungasarkhel]

Then what to do if i take input of spwm signal and just split it in 2 different output respect to frequency.

[bhuvi]

Resolution formula in terms of voltage is Full scale range/2^n-1

Regarding hi res audio...if the signal passes from digital to analog in high quality (flac 24 bit/96 khz), then from analog to digital, and then from digital to analog. will the queality of the signal be the same/better?. Digital audio player with its DAC - ADC - DAC/ AMP.? I wanto to use a DAP as audio source that can play lossles formats in hi res (24 bit/192 khz), and use other DAC of other divice that sounds better. The DAP doesn't have a digital audio output. So I want to conect the DAP to ADC and then the ADC to a DAC/AMP and get the best possible soumd coming from last DAC and the high resolution format (24bit/96khz).
