Linear Tech Current Source (LT3092)

Conrad Hoffman · 31st May 2009, 01:15 AM

Maybe this is old news, but I just saw the LT3092 and thought there might be some clever audio uses for it. Anything from super simple low power class A headphone amps, to better current sources in conventional designs. Anybody else thinking about using it?

Nobody? Given the other threads on current sources, I'd have thought it would be more interesting. I'm going to order up a half tube of 'em and see what they can do.

Interesting, indeed. Maybe I should take a closer look at this device?

Looks like a better LM334. I think these things are not popular in audio because there generally isn't a need for high accuracy or small size, so it's cheaper to build one from a handful of discrete parts instead.

Thanx Conrad... i was going to order some LM324 to try as low current CCS on LTP front ends where the IXYS 10M45 isn't really happy. This looks like a better bet.

Well, my distributor says I can't get 'em yet. Soon...

Neat!

I was thinking of using it as a current source in the first and/or second stages of a triple darlington output stage (no more calculating/guestimating resistor values, just use one of these!).

Samples/stock are not available yet (according to findchips.com) - I hope they become available soon!

Anyone ever get around to experimenting with this IC?

I have an op-amp based circuit I would like to bias into Class-A with these, but I read another post on the forum suggesting they are not good for dynamic AC signals.

i'm interested in any results with them too, I spotted them along with some very interesting integrated active filter building blocks when I was at the linear site the other day. maybe i'll just bite the bullet
