Building the ultimate NOS DAC using TDA1541A

[rakeshpoorun]

I am interest in getting one...

I am interest in getting one, dependent on price.

I'm interested x2

 

[Zoran]

me too for 2 pieces
again dep. on price
thanks 🙂

Hi,

I'd take a couple of grand.

Hi,

I have received the TDA1541A S1 dac chips. Please see my post in the swap meet forum:

New Old Stock! TDA1541A S1 single crown for sale

Lucky you, lucrative business...

I’ve just dipped back into this thread. One day hoping to find a decent dual implementation for this chip - DIY board. Soldering A-OK. Time, not so much now! New son!

Best wishes to all!

Congrats, later you'll have even less time 😉
I am also looking for a I2S to dual simultaneous TDA1541A PCB to be assembled DIY.

Have you checked out Ryanj threads? I believe he has dual I2StoPCM pcb that he uses to drive 2 of his D3 TDA1541a pcbs.

Use the CPLD board from China.

I can sold one IanCanada I2StoPCM v1.1, I have three brandnew. (works with tda1540, simultaneous mode TDA1541, AD1862,1865,PCM1702, 1704


but it must be slaved by a master clock with uf-l : made to work with Iancanada Masterclock or later FifoPi... all i/o are uf-l

Use the CPLD board from China.

My plan is to use that board. Actually I am looking for the DAC board itself. My goal is a dual 1541 board where each DAC operates in balanced mode (L+/L-, R+/R-), accepts simultaneous offset binary, and perhaps there are onboard shunt regulators. OK, maybe I will design it, or just link the components together on a veroboard.

Thanks! Don’t I know it! 😀

I’ll check out the boards. I have built Pedja’s DACs (an Aya is still in my system doing sterling service today), and was looking to see what else there was out there with two chips. John’s suggestions in this thread really piqued my interest.

Philips 7220 was not a jitter contributor ? Myth ?

 

[lcsaszar]

Not with proper reclocking and PSU filtering.

 

[diyiggy]

cool 🙂 . Thanks.


I have tons from my broken cd players (aka Lampizator disease illness)

Hello - I am in the very preliminary stages of a TDA 1541A design. I have read good things on Sowter 1465 I/V interface transformers. Anyone has experience using them? They are meant to generate a line-level output with a high-value resistor across the secondary, however seems one could use a lower value resistor and present the TDA 1541A with a smaller load at the cost of output voltage and add a gain stage to the secondary, I'm curious if anyone has experimented with both configurations, thank you 🙂

 

[diyiggy]

Many tested and man came back to active I/V . There is no real evidence this (and other) transformer is the best at this job. This is not it's bad, it's just there is better for this chip.



Seing your avatar, I would try a tube for the I/V task (Thorsten Loesch) .
