Could you tell us a bit about the CCS? What parts to use for CCS only, where to take the signal off, how many ma are available?
thanks.
thanks.
Sorry, I cannot figure out where the output location is for the CCS, or which parts I would minimally need to install for *just* the CCS.
Oops... added some text about this. You can also see this in the schematics. Check the variant called "Without CCS". The parts are marked with red crosses.
Thanks!
Just to verify then ONLY the red parts that are crossed out need to be installed to create the CCS and R2/R3 are also not needed?

Can we use the CCS to bias an external op amp into class A *and* use the buffer at the same time?
It looks like we cannot, since the input will be the CCS.
Can it run from 10V if it is only going to swing less than 2V?

Excellent! I now wish I bought a few more.
Though I don't know how to calculate the value of R4 vs Rail voltage.
I guess you want the same current to flow across R4 depending on voltage?

SMD is good therapy. These are very nice boards Per.
Tinitus - I have ordered slightly too large 'lytic caps for C6 and C7 it's an awkward fit. Apologies for this, I may get correct ones in the new year. I would advise soldering C7 inside pin before R7 maybe.
