Hi, The LM was a very different ln3900 of op amp. I probably have few AD’s around, but i dont think i have any LM’s around anymore. Datasheets, Manuals or Parts. Replacement Transformer Started by ncag 59 minutes ago Replies: Neil Groves New Member Nov 8, Redesigning them for other op amps probably wouldnt be much of a problem really.

The LM is a high speed version. You must log in or register to reply here.
Hi, I’d be careful about using an AD for a replacement. It’s very different than the LM Km3900 am surprised to see them in circuits today. Is an LM a good replacement for an LM? One of the cool things about the LM is that the input voltage can exceed the supply rails without a lot of fancy stuff.

Datasheer here to register now. We can call the input resistor R1 and the resistor to ground R2 and the feedback resistor R3.
It can not be replaced with a LM op amp. For one thing, the input bias would be different.
I seem to have blown out on at least two things here, i’m gonna scrap that project, build something else i need then come back to it using a different circuit. Replacing a daatasheet pin leaded inductor with a 2 pin Started by gkmaia Yesterday at From the LM data sheet it looks like the three amps with two caps each are just bandpass filters.
To participate you need to register. That’s what a specific timer of mine does. Thus you could look for the presence of line to speaker levels very easily and even filter the hiss. This may not be the ideal setup, but it might dagasheet work.

Hi again, Yeah i remember these from back in the ‘s. Back in the 80’s i did.
