hello Latin Friends

I think that configuration of CFP-VAS
Cannot have more than G=5
So R7 need 800*5=4Kohm max
Also may be need another stage on input with G=5
Total gain 5*5=25
but first is better finish two stages
---> It's important use the same devices of final Output Stage as drivers
that is the "natural gain compensation" criterium to equalize the Hide Gain

Thank you... i will try a single stage to give me the added 5 of gain

thank you.

regards,

Carlos

ciao

only a pair of P/N channel
can give a compensation

look at the diagram of principle
summations of the values are indicative

gain G=5

global gain G=5 is enought if you have a Preamplifier
that can give a 12V Peak (OPA134)
