Default LM386 alternatives?

Hi All,

I'm looking at a headphone amplifier kit which uses an LM386 as the chipamp. Could anyone suggest a better quality amp that could be swapped in the same circuit?

For reference, the circuit is shown in this document:

Thanks!

The best alternative would be to ditch the LM386 and find a circuit that doesn't use an output capacitor.

Why did you choose that project?

If it's for sound quality, something like the buffer combo we usually talk about here, with OPA627 + BUF637, will sound a lot better than this circuit.

I'd recommend looking at Tangent's mint or pimeta boards.

http://www.tangentsoft.net/audio/mint
http://www.tangentsoft.net/audio/pimeta

Both of these are reasonably low cost and fairly high-end compared to the "single op-amp" based headphone amplifiers.

I don't have any association with tangent other than having bought his products and being a satisfied customer.

Thanks! This is exactly what I'm looking for. I did find another kit, but it's probably overkill:

Thoughts?

The LM386 isn't an easily swappable chip. It has the gain internally set and the pinout isn't "standard". You won't be able to drop in a replacement directly without changing the circuit.

It looks interesting indeed. Probably an Erno Borbely design. You will have to spend something more on the supply, which on the other can be a battery one.

Tangent's or Audiokits' are probably the way you should go for serious headphone amps.

I agree. You can build quite a few different types of amps from there. If you're sure you want to go with an op-amp based headphone amplifier, check out the "chu moy" .. You can probably build one for less than $20, including the enclosure (the ever popular altoid mint tins).
