ADC design for 16bit / 48Khz audio
« on: August 11, 2024, 05:25:06 am »
I need help selecting ADC chips.  I would like to build a couple ADCs for 16bit 48Khz coding with AES/EBU output.  Balance or differential input would be key.   I would like word clock input and output.  A stereo channel pair would be ideal.  There must be a single chip solution, no? Way back I know Crystal Semi made a single chip codec, but I don't think it had word clock and was made for consumer CD.  I've looked around at eval boards but those I found where higher priced than I wanted. I use Crystal Semi eval boards for DACs today but I was given them by Crystal Semi years ago.  I know people are using different TI chips. I'm looking at their product selector and I was hoping someone who knows those chips could narrow the selection for me or maybe point me at other choices.  I can code a micro if needed for setup but would love it to run standalone with pushbutton selections.  As some of the data is headed to either ADAT or TDIF, I know there are custom ADAT chips available for up to 8 channels I was thinking of incorporating too. 

Thanks

Jerry

I would take a look at AKM  in Japan.  They are one of the biggies in this area.

https://www.akm.com/us/en/products/audio/

They had a fire a few years ago but I think they are all caught up with that.

AKM was starting to make A/Ds and D/As like the Crystal Semi parts but were cheaper back around 1990 as I remember.
I just tossed my old Crystal Semi eval boards

You can also enter some of the terms into parts search engines like...

Search Digikey for I2S ADC.  There are a bunch of them, including with 2, 3, or 4 channels.  E.g.
