A good way to reduce R-2R DAC linear error

Instead of endless discussions one should try

You first.

I need 32 x PCM1702 for a 16 bit stereo DAC.

Anybody ? 😀

How much are they?

Why not ask Edmund 'Laptops and Lederhosen' Stoiber for a grant, Bavaria seems to have more money than the rest of Germany combined.

Ahh! Another insightful post and another giant step forward for the project by, ehh, whoever, from, ehh, whereever..

Ok Mr Sarcastic, are YOU going to give him the chips, nevermind the A/D's ????

OK, but it would help if the 'cop' smiley would look more sternly. 😉

May I assume Jan and I are in the same boat?

That's more like it! get some respect!

If so, you better get ready to swim...

Jan Didden

OK, OK, I'll get back to topic.

Victory to you on a technicality I think as, alas, I cannot think of a reply that won't fall foul of the dibbles.

At $18.60 each for the lowest grade, it might be an idea to forego the dacs and just build your own precision current sources.

Current source DAC

At $18.60 each for the lowest grade, it might be an idea to forego the dacs and just build your own precision current sources.

I would expect that the chance for succes would be higher when building a complete DIY Current source DAC.

Would something like this be useable for this purpose:

I would have thought not but you best put it to AD1865 and Bernhard.

 

[AD1865]

I use best DAC

WM8768? why not use PCM1792/4? IMHO, Delta-Sigma DAC is not better than R-2R dac in sound quality, although its spec is better.
To Bernhard, using 4 pcm1702 for balance is enough, And to validate if only need to test 38 code for each PCM1702.

 

[Jocko Homo]

Don't like delta-sigma, eh???? Then stay away from the "current-output" '179x series.

Maybe you can find what you want in a local shop...........for local people only..............[joke]
