Discussion Overview

The discussion focuses on selecting appropriate audio ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter) for a project involving the conversion of analog audio signals to digital form and vice versa. Participants explore specifications, input types, and practical considerations for achieving desired audio quality, with a maximum sampling frequency of 44.1kHz and resolution between 10 to 16 bits.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • Some participants express uncertainty about how to choose between numerous ADC and DAC options available, noting the complexity of specifications.
  • There is a question regarding the differences between single-ended and differential inputs for audio converters.
  • One participant mentions the need for higher requirements due to the nature of audio signals, suggesting that simplicity may not suffice.
  • Another participant suggests using a CD player with built-in digital output to simplify the project, questioning the necessity of an external ADC.
  • Some participants indicate that they have been searching for suitable ADC options for an extended period without finding a clear choice.
  • There is a mention of the company Burr-Brown, which previously produced DACs used in CD players, but no further details are provided.
  • One participant emphasizes that converting the analog signal to digital is part of their responsibilities and expresses the need to find compatible ADC and DAC components.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to selecting ADC and DAC converters, with multiple competing views and uncertainties remaining about specifications and project requirements.

Contextual Notes

Participants express limitations in their understanding of the specifications and requirements for audio ADC and DAC, with unresolved questions about input types and the implications of audio quality on component selection.

Audio ADC and DAC is needed !

I am looking for Audio ADC and DAC.
Anyone can give their advice on choosing these two converters?
I am planning to convert the Analog audio to Digital Signal (vice versa) in 10 – 16 resolution bits and fs max will be 44.1kHz.

what is the different between single-ended or differential input for that?

What have you found so far in your searching the Internet? You have used some good keywords in your question -- what happens when you google them?

Take a look at the website for Analog Devices -- they should have some good devices and application notes to get you started.
 


At first, i thought it will be easy to pick one ADC and DAC from net or Analog device, but after i look for the spec, it show upto 100 choices...
so i wonder what shud i take more care on it.. i plan to make it as simple as well... but due to the signal is audio, so it may need higher requirements? or anything will does?

To refine your search, I googled Audio ADC and DAC +44.1kHz, and got lots of good hits:

http://www.google.com/search?source...GLL_enUS301US302&q=Audio+ADC+and+DAC++44.1kHz

Have a look through that hit list to see if you find something you like. You need to find a good Application Note on how to actually build something like this. It's not an easy project, if you want good audio quality in the end. What kind of projects have you built so far?
 


Actually, i need to convert the audio output from my CD player to digital form then transmit it wireless by laser...
let put the quality aside, as least i want to convert it into Digital.. i looked for the ADC for 1week d... but i really not sure which will be the suitable 1... even 8 or 10bits also can.

Can you just use a CD player with a digital output built-in?

That would simplify at least that part of the project.
 


I know at one time the company Burr-Brown had DACs that were used in CD players.
 


Thanks for the links.
but i think to convert the analog signal to digital is part of my responsibilities.
anyway, still need to figure out the way to get compatible ADC with DAC...
