What can I make with an LM380N?

MunkeeVegetable · 1st October 2005, 05:21 AM

Hey guys, I have 4 LM380N's sitting here that I got from a nice person, but I don't know what to use them for.
Anyone got ideas/schematics/etc that I may be able to use?
I'm thinking preamp or something, or maybe a headphone amp, don't really know (that's roughly what they're for, right?)
Any help is greatly appreciated,
Cheers,

You can download the datasheet and the application notes from www.national.com There you can find something maybe but why don't build something that you want instead and then choose IC's?

I didn't choose the ICs because I was given them

Thanks for the link, I'll check that out.

What to do with them..........

Uh, I dunno..........they make a good oscillator. Although not on purpose. We used them for the audio on service channels. About all they are good for. Poor distortion, really slow PNP devices inside. Pretty much useless these days.
