I will do it some time but I am afraid it is the same thing as with the clock...

till · 5th June 2004, 12:38 PM

none of all you old philips DAC fanatics did try this?

#90 circuit measures swing of ~1 to ~1,6 V on my scope

is this ok or should i change before building 6 of them?

And it works with schemtaic shown in #90!

now for the discrete inverter for the - DAC

Huh?
What?
Me?

My dacs have been quiet, I've been fiddling with phonostages and amps lately.

Bernhard has been fiddling with clocks.

this is nothing with clocks, its preconditioning the digital input lines to the chips for minimal crosstalk and influence on the output.

I know till, I've read this thread some months ago.
I was joking.

Bernhard has beed scavenging oscillators.

Hi till,

did you built it or this is just a simulation ?

Did you built this one ?

ZERS · 23rd June 2004, 10:34 AM

Oups, I forgot the attachment

Bernhard · 23rd June 2004, 04:54 PM

And how does it sound compared to standard cmos/TTL levels ????

till · 23rd June 2004, 09:16 PM

i did not simulate it, some people who simulated posted allready. I built it.

I don´t want to give comments on sound now, because i feel i listened and compared not enough to tell something about yet.
