Hi Mozfet,
I am using the OPA604 for IV with TDA1543. OPA2604 is a dual opamp of the same type.
AD8610 with +/- 12V supplies might also be a nice contender.

Lightbulb OPamp for IV

Hi Peter,
I did try the OPA627 for IV with the TDA1543 NON-OS. In fact I tried a whole bunch of opamps from my shoebox full of it: AD711, LM6172, AD797, OPA2134, OP249, AD827, AD811, AD844, OPA603 etc.

Default Kwak DAC

HI Elso,

Just read elsewhere about your preference for the TDA1543 over everything else, I presume this is with your own Acitve I/V stage (using OPA604??) any diagrams? I have a few TDA1543 and I confess I like the idea of a great DAC from this inexpensive component, also while I have your attention any chance of your latest clock?? I've been ill for a while and never had a chance to try the (version 4?) you kindly sent me.

Hi Peter,

How did you come up with the idea of the 14 Caps on the TDA1541A executed like that? (Genius!) I think I should give up on Electronics and take up Pottery! I wont even mention that work of Art you call a Gainclone!

OPA627 is very suited for this purpose. One of the best I know and I tried a lot. Please don't forget to remove the compensation cap that is usually mounted when NE5534 is used ( 22 pF ) because OPA627 is compensated internally. Don't be tempted to use OPA637, it is not the right one on this spot.

For NE55232 there are a lot of suitable replacements. OPA2604 is OK but there are better ones ( all with other strong points in which they excel ) out there. This has been discussed many times on this forum, please use the search function on NE5532 and I am sure you find the sometimes heated discussions. AD826 is not bad either.

Whatever opamp you use, please decouple fast(er) opamps well. They'll thank you for it by doing their work instead of oscillating or exhibiting other nasty side-effects.

Hi Mozfet,
First opamp is now OPA604, second opamp discrete. 3k3 from Vref pin to ground.

Default Thanks!

Thanks for your input guys, it is appreciated, and Jean Pauls point about the compensation caps on the 5534 is a valid one, it is very easy to forget about this point when so many will be SMD.

From my experiences it results ,that best arrangements DAC
with speed of exit's tension and short transitory time
: OPA are 627,AD 8610 ,AD825, except
Are and it can act different arrangement operating OPA604 well, 134 , it is132
Good checked myself what plays in best one's cd .
On my side it is pare of examples of use of arrangements to to get high quality of sound.
I'm sorry behind English , computer translator - understanding incomplete
