Metal can audio opamps?

lil' knight · 17th January 2013, 03:19 PM

Hi guys,

Just wondering if anyone could do me favor listing popular audio opamps that are packaged in the metal can?
I only have experience with the lme49710/20, opa627/637 .

Anything else should I pay attention to?

Cheers.

I know the LM348, and in fact I have 3 of them.

Bust isn't LM348 a quad opamp? How do you squeeze that into a TO99 package?

Sorry , typo, they are LM748CH from ST Microelectronics. Lot # 98805.

In the early 70's I used metal can LM741. (8 pin).
Way back then, the cutting edge of technology.

RCA CA3140 - bought some in High School - used them to fix a Mech E analog computer dynamics demo box in college

Thanks. Those parts are hard to find these days.... Anything worth looking at, especially from BB or TI?

LM4562HA shows in a dual in a can, but good luck in finding stock. You'd probably have to buy 100 and wait for the factory to make them. Get in line before the economy heats up.

LM318 came in a metal can.
