re- pcm56

I can replace NJM5532S
with opa627 with adaptor without modified circuit of my cd player ?

please look the file schemeats add

The usual suspects, opa627 on dual adapters ?

Bernhard · 2012-04-17 10:07 pm

Do the opamps have 2x4 pins or 8 in a line ?

8 in a line.

SIL single-to-dual Op-Amp Adapter (p/n 040701)

An externally hosted image should be here but it was not working when we last tested it.

re- pcm56

Very thanks for your help,
please the last questions :

Once installed opa 627 with the adapter does not have to do more 'anything?
resistance, capacitors must not be changed? ok?

where can I buy opa627 ?

thanks luigi

For you: Arrow Central Europe, Arrow Northern Europe, Digi-Key, Mouser Electronics...

And make sure that you solder the opamps to the adapters correctly and insert the adapters in the pcb correctly. Pay attention to the pin1 markings on the adaptor.
Also ic607 and ic608 adaptors need only one opamp each. See schematic, one output goes nowhere. ic11 is for headphones.

re- pcm56

ok, very thanks,
the last question :
you raccomended the improvement across the dac board would have power to dc battery ?

..................opa627 AM.AP,APG4,AU, BM ????? which ?

I have never tried battery power supply.
You would need many batteries...

re- pcm56

but my dac's main bord work 5 volt -12 volt
I am in error ?
please
see the schemeats
thanks luigi

Those are different packages. The adaptor from previous pages requires SOIC (letter "U" in name).

The "2k5" in the name means it comes on reel of 2500 - irrelevant for you, since you don't use automated process. The "E4" and "G4" are irrelevant for you also.

luigilamarca · 2012-04-19 5:11 pm

ok, thanks .

how many njm5532s to change?
four?

but .....the pin configuration of two opa njm5532s and opa627 not are egual ?
with adapter it are egual ?

NJM5532s :
output pin and pin 7

opa 627 : output pin 6 : Confuso:

luigilamarca · 2012-04-19 9:37 pm

re- pcm56

Dear,
'I do not understand, fording the data sheet of opa pins are not equal
NJM5532s :
output : pin 1
output ; pin 7

OPA 627 : output pin 6

perhaps with the adapter all is' right?
us before you make a fault in the cd

please see the data sheet and help to my.
thanks luigi

Look close to the adaptor that I pointed on the other page and you will see...

re- pcm56

...I understand ..the adapter converts the wires to the
correct position. : Rolleyes:

very thanks luigi
