DIY TDA1541A PCB "D3" - Page 90

Mark,

It is a very good point. You can successfully do this entire build with a fine tip. Doable, but difficult. Because of the affordability of air stations, I'm trying to push people to make the small investment with the idea that their success rate will be higher.

I did solder the U.fl's with a tip. Again, doable but you gotta be quick and good!

Cheers,

Greg

Hi androa,
I'm just at work at the moment. I'll get on to it when I get home. Sorry for the delay.

Is it possible to use Battery power supply for 26V input? What are minimal to maximal response of 26V voltage input?

Thank you.
At first i must confess i am not so that huuge fan of tda1541. Till now i didn"t hear any dac or cd player or modified that totally fulfil my apetite. Yes it is nice sounding dac, but not what i want. I listen very often to total dac that i like very much. And i have this sound as my reference in my head. For now i listen to es9038pro heavy modified dac because Ian combo is not enough for me. At some way i got Tda1541A and Tda1541s1 and D3 is first design that i am interested in.
Despite so many tda1541 designs approaches, it is very hard to read all treads and find out the reasons for using some ideas for D3 dac. For example why lp5907 ...4,5V. This reg is limited by max 6v, so using any Accu supply is impossible. Why not lt3042? and set to 5V ...why 4,5V. Maybe it is somewhere written ...? My idea is to run dac only battery supplied.
I have a lot of lifepo and lion accus that show good results at Ian streamer dac combination. Also our Rpi streamer is Accu suplied with linear regulators. This was the only way to totaly eliminated digitaliss , digital harsness that i very often hear at streamer (rpi or computer or comercial products) as a source.
As i see no specific ideas for using input board before i2s board... one possibility is to use Waveio as ryanj, or Jlsound usb that can be directly conneted to dac because it already has simultaneous output, but i will also like to use spdif and coax and i2s for amanero...

Hi androa76,

If you would like to use a 5V reg for the attenuators just make sure it has the same pinout. The extra 500mV wont change the operation point of the attenuators very much. The LP5907 was used because it seemed to fit my design requirements and was recommended.
