I was just looking over the schematics and BOM for the Carrie.
It has some odd component choices.
The BOM specifies a dual rail version of the DCP01 even
though it only uses one of the output voltages.
A single rail DCP01 would have seemed to be a better choice...
If using a dual rail DCP01, it would seem to me to be a better
design to get rid of the TLE and extra op amp for the rail splitter
and just have a proper dual rail supply.
This is not aimed at anyone, I'm just rambling...
Edit: Oh, and lastly, it uses an 8 volt regulator giving +- 4 volt rails.
The op amps like 5 volt rails...
Why not a 10 volt reg or at least a 9 volt reg?
