Hi Gianni,
good job!
Did you take some special care about the EFC voltage stability vs.
temperature?
I had some trouble in that, playing around with a LPRO101.
It seems that a good voltage reference, a pair of high-precision resistor
at the ends of the multiturn pot to reduce the voltage span, end a good
multiturn pot, was not so goodâ¦.
I do not know what was wrong with thatâ¦.
Anyway a lot of fun! :-)
