Question 4558DD Datasheet

Does anyone know where I can find a datasheet for a JRC 4558DD chip?

Edit: sorry, my crappy dialup connection decided to be dumb while uploading the file. I think the file is too large anyway, though. Just do a google search like Carlos suggested, and it comes up quickly.

A tip for finding datasheets:

www.digikey.com
www.newark.com
www.mouser.com

You search most parts there and usually datasheets applied.

Hi

Wonder what is the attraction of the Jrc 4558
Ics? Always thought they were 741 style clones and
as old as the hills. I have three in a nice C22 Aiwa
micro preamp and was planning on replacing them with
B&B or other more modern Ics. Am I missing something?

Yes,
you're right - old as the rocks.
If they're used in audio signals better to replace them with 2-op chips (opa 2132 or opa 2134 or linears).

i think kinger is in search of an replacement...

Kinger asked for the JRC/NJM 4558 datasheet, that's all.
I don't think there's any attraction here.
It's hard to pick a worse op-amp than the 4558.

Hi,

Yes Carlos, like you I believe Jrc4558 ICs
should be left to non-audio applications these
days where they do not defile our ears! It was
just that the S Korean master of miniaturisation,
Sijosae (Jeoing Seob Shin) used them in a cough
lozenge box size headphone amp if I recall correctly.
Perhaps he was experimenting with what
was at hand in his tool box ! Perhaps he was
just making a hearing aid for a poor friend in the North!

So what IC replacement in your opinion would make
a circuit with 4558s to sound acceptable
in the 21st century with minimal other circuit
changes?

regards

AnthonyPT

In what kind of circuit?
I've seen 4558s as I/V on CDPs, you know...
The recommendation may depend of where do you want to replace that op-amp.
