Just looking for some user experience on bypassing the power pins on the LM6171
I believe the CarlosFM method is 22-100uF electrolytic with 0.1uF ceramic as close as possible (which I've used happily with other opamps - thanks Carlos!). Datasheet shows a configuration with a 2.2uF tantalum with 0.01uF for the LM6171.
What has worked well for you with this chip? |

| 4.7 BG N without any other aditional bypasses. |

1uF low inductance film like cap "ERO" MKT 1822 soldered onto the pins also works and sounds good. This arrangement and a battery works well with no further aditions needed.
best avoid using sockets - they could well cause oscillation.
I did it dead bug style.

That and also a 100~330nf directly across V+ and V- pins works wonders.;)
No problem with sockets and the LM6171 if you use the small ML ceramics right on the socket's pins to ground.
And btw no need for ultra-fancy caps to have excellent results.:cool: |

Thanks all! Good to know it's not hypersensitive - you just need to treat it properly. :cool:
I'll probably start with the method I know, and experiment from there.
I was going to go without socket (which I don't like to do, but wanted to avoid the extra capacitance). Maybe I'll give it a try with some good machined sockets first, keep the caps as tight as possible, and see if I can keep it out of oscillation.
And I definitely won't forget the 100-330nF from V+ to V- :) |
