Re: Re: Re: TL431
Guido you are confusing me.
The LT1431 from Linear Technology, as mentioned by Massimo, has indeed a earlier rising impedance curve.
The TL1431 from Texas Instruments has the same impedance curve as the TL431. Even the schematic given by TI is the same. The TL1431 seems to be just a tighter speced TL431.

The schematic is too big for attaching on this forum. I want to mail it to you but you have to leave a mailadress since I can't attach anything with the Mail function of Diyaudio.com.
So for the last time, leave you mailadress in a way like this to avoid spamming:
dennis_nospam@hotmaildotcom.

jean paul,
At the risk of abusing your patience I would also like to have that Kusunoki article since I'm considering also of redoing my S1 DAC.
I'll leave my address at your email,
Thanks

Hi Paul,
Thanks for your reply. Sorry for not giving you my email address. Please send the scans to denniskmwong@ctimail.com.
Thank you very much for your help!

Re: Re: Re: Re: TL431
Hi Elso,
Either way, both are no good for audio, at least to my knowledge. I'd prefer flat impedances at least straight up to over 100 kHz when used in an analogue circuit.
best regards

You keep confusing me!

The TL431 is used in the recommended power supply for your clock by Cuno Snoeren:
http://www1.tip.nl/~t708955/schem/xoschema.jpg
Did you change your opininion or do you no longer approve this circuit for your clock? If so what do you recommend now? Are we talking at cross-purposes???
😕

(Scroll down to CD-player Upgrade II). The circuit is also in your PDF-file"The why and how of low-jitter oscillators"

Elso
Cuno's circuit is a fine sollution, easy to build hence acceptable for most people and does not need any adjustments.
My own power supply is different, more complex, needs adjustment and therefor not the best compromise for the average customer
My supply noise is below 5 nV / Sqrrt Hz. I never optained noise measurements on Cuno's supply.

Re: Re: Re: Re: Re: Re: Re: TL431
Dear Guido,
Thanks for the reply.
Now the sharp-eyed reader sees a TO-220 voltage regulator, some caps and a pot on your circuit and is wondering how to achieve 5nV/Sqrrt Hz noise?
😕
Don't feel obliged to share the schematic....😉

Hi Jean-Paul,
Why not?
😉 😉
5nV is a quite intriguingly low value!😉

i was wondering whether you could forward the schematic over to me . Thanks alot

to much spam coming into my mail box no point trying to avoid spaming 🙂
