Op Amps: Digital to Analog Conversion

In this video we examine basic digital to analog to digital conversion circuitry including weighted summers and summers utilizing R-2R networks.

Just wow!!!! Great and simple explanation, thanks for video. Don't know why people make it very complex.

I'd worked out the doubling resistor summer but can see the problem. The R-2R solution is very elegant, I like it. Thank you, really clearly explained.

I don't understand why they don't teach like this in class. They just have slides with awkward equations. This is so much simpler and takes less than 10 minutes to teach.

Brilliant video. Thank you so much Professor Fiore.

Thanks, exactly what I'm Looking for.

Great video. Can you please discuss some useful applications of DACs with op amps?

What value of Rf should be used? And where do we measure the final adc voltage? Is it the voltage across Rf? Thanks

I wonder how the output would be if We Don't use the Amp, When all bits are at a high state.. Would it Be 5v? In other words, is the Amp job in the circuit is to smoothen the signal only? Or is it necessary for the conversion..
