Don't tell me that a LM386 is bad without telling me why and what to replace it with. If you don't, then you're not actually helping me at all, but rather it just sounds like you're spreading FUD.
- cr0sh 10y agoAbout the only thing "bad" with the LM386 is how finicky it is with component selection and layout. It's a great little amp when it works well, but sometimes it will go dopey on you just looking at it sideways. It actually works better in a PCB situation (breadboarding is where it can be wonky in operation - ymmv). As far as a replacement part? I don't think there are many alternatives there (at least with the same size, and easy to configure - there are a few stereo ICs I've seen used for class-D amps, but they weren't as simple to use or as small).
- cylinder714 10y agoThe very first article of the book More QRP Power discusses surface-mount tech and why amateur radio people should embrace it, and the author specifically mentions an SMD chip with better specs than the LM386...but I don't have the book handy. I'll search for it later.
