Theory about DACs

Simo88 · 17th April 2010, 04:23 PM

Hi,
i am looking for some articles about dacs, could anybody give me some links?
I am searching some example of basic circuit and the answer at questions like "Why paralleling N TDA1543?" for example...

Thanks!

I suggest you go to the web site of Analog Devices. They have many application notes that may give you the information you seek. Texas Instruments is another.

the theory behind paralleling dacs is the same as paralleling anything. the idea is to throw twice (or however many) instructions at a problem lowering the error count when it is divided by the clock

When it comes to paralleling dacs. Other system distortion must be below 0.00001 before you can expect any real improvement. If distortion is below 0.1% critical part in to deliver current and not make your amplifier clipping.

Ok thanks everybody for the answers!
Are there any good book about dacs, i mean examples and circuit?

However silly it may seem (to someone), I would start with a Wikipedia article about DAC's. It will give you a good heads-up on the issue as well as some decent references. As you discover more and more, use google to dig in even deeper.
