Looking for a Power Supply Design for use with DIY DAC's either weblink or book. I'm trying to come up with my Circuits dont really want to use someone elses design. since i feel i takes aways from the whole diy thing. I'm not agenst the use of proven Designs or Circuits. just wanted to build one of my own. if you guys can help with info please post thanks
There are probably no answers because this topic has been covered in depth here. I searched and found 179 threads that mention it, just in digital.

I assume you did search before you posted your question, rather than just ticking the box?

If you want a new design, then make something and post it here for comments.
I gave you the links to read. I'm not the one searching for the info, you are. I just tried to point you in the right direction.
fresno Bob said:you post a link with links in it if you have an idea of what it is im asking then why not just point right to the info..

I for one do not understand your request. You want a link to design information but don't want to use someone's design?
Building something that’s never been made before is quite a challenge.
From my understanding you are not seeking to copy an existing design which is of course the best way to learn. The only way to achieve your goal is reading what others did and distillate something that might suit your needs. You got a bunch of links from Pinkmouse to start with and tips from other people as well. Then, with paper and pencil or, like the modern guys do, with some specially designed computer program, you could draw your findings and calculations into a schematic.
Next plausible step would be to post what you came up with and ask for opinions.
You’ll be surprised what help you will get from the experienced among us.

A bit odd request but start with studying the datasheet and available applaction notes for the DAC in mind and also for other DAC's. Check also evaluation boards. How have they done?fresno Bob said:Looking for a Power Supply Design for use with DIY DAC's either weblink or book.

You have a couple of options:
1 3-pin regulator like 7805 and such
2 Shunt regulator like LM431 maybe with some extra transistors with or without feedback
3 Some discrete built series regulator
Since you are feeding a digital circuit with a rather high content of harmonics in the range >100 MHz you must have in mind that the regulators may be able to handle this.
peranders i beleave i have said reg's in a parts bin will however look at the data sheets on the dac chips ect.
Netlist Thanks if i come up with a Design and need it looked over i will post it.
pinkmouse Thanks for not helping. i did not ask the members here to build it for me. and from what i have read most are using others Designs or making their own. if you have schimatics for me to look at post it.

Have you tried www.google.com ?
Why don't you test with "voltage" "regulator" "DAC" "digital" "analog" "converter" "audio"
http://www.google.se/search?q=volta...onverter+audio&btnG=S%F6k&hl=sv&ie=ISO-8859-1
Maybe you can find something?

This is what i have come up with sofar as to what i would like to do.
Dont know if it's possable still reading some stuff..
I/V
Current to Voltage Converter
· Resistor based for low distortion
Power
Isolated Digital and Analog Power Sections
· Low noise by isolation eliminating power spikes in analog section
· Separate local linear regulators for left and right sections
