Hi guys, just wondering if anyone can suggest a replacement for this chip that is quieter. I have a handy little headphone amp I made a while back based on the 386, but it really hisses.
Just thought I'd ask before I go trying a different circuit.
cheers.
Are you sure it is the LM386?
The LM386 is just a power amp and would amplify any noise already present in the signal.
JRC386D is supposed to be less noisy. Try running the circuit on 12v, should give you a cleaner signal with less noise (make sure all the components are rated for 12v).
