How Do DACs Work? - The Learning Circuit

I really don't think the output wave is stair stepped on a proper audio DAC. Had a look at the output on a scope?

Actually supposedly dacs have a lerp style wave smoothing (maybe using capacitors). The output is supposedly smooth.

That this video is wrong on the audio part is truly sad

Try using a multiplexer (analog)

Awesome tutorial ❤ in my opinion, modern audio dsp has gotten the sample rate algorithms and interpolation algorithms almost perfect. But the amplitude and saturation produced by variance algorithms, is just not there to my ears. Which is an awful thing to say since dsp engineers have done monumentally amazing work haha

Thank you! I like your series to explain electronics in a simple and informative way. Looking forward to see more.

..., 32, 16, 8, 4, 2 & 1

Please any one can help with VT25-373-99X9 data sheet

What is the use of chip and crystal Osilator on dac if only op amp and resistors are used. No one tells how software works with the frequency with the dac. How switching is done.

Most excellent!

To the point and very informative. Just what I was looking for!

Hi mam ❤️
I am from India 🇮🇳🙏 very helpful your video

Thank you mam.

The MSB is that have the smaller Resistance I think it is flipped here

Awesome delivery, easy to understand, learned a lot. Make more. You’re awesome!

This is wrong. Audio DACs (and ADCs) are bandwidth limited to an appropriate range for the sample rate. The reconstruction filters low-pass the output of the voltage stage, eliminating high-frequency content (the stairsteps). The output signal accurate represents the input signal with the addition of some amount of quantization noise. Nevertheless the signal to noise ratio ( and dynamic range) of digital audio exceeds that of vinyl.

is using High resolution dac only way to creating smooth and real analog output ? Is there any other ways to get real analog signal from a device?

After watching this, I now realize that the DAC I created for a new project is actually a binary-weighted DAC and not a ladder DAC like I thought it was. Good thing to know!

0' s place?

Even a vinyl LP is a compromise from an original analog signal due to the need for the RIAA curve. LPs have a limited tolerance for low frequency signals because the stylus can jump out of the groove if it is too wide. So to compensate, the RIAA curve was created. This means that the analog signal coming off of an LP still needs to go through processing before it is reproduced. Even if this processing is purely analog, it will still not be a perfect representation of the original signal.

Great video!

Sure wish you did more of these. The way you explain them is very easy to understand. Miss the show also.

But thankful for these learning circuits. Thank you. Ive learned alot in the last year watching all these and all the old one. Always had repaired when I was a kid

And now full time working as its the only thing i can do now. Glad to be learning again. Love electronics.

Keep up the great work.

Very good

Element14 videos with KAREN are the best!

Great video, thanks.
