I have designed a schematic with 3 circuits (same configuration) with ampli ops . at the end of each circuit , i put a 3V zener diode because i inject the signal into a uC .
the problem is that :
- when i don't use the zener diode , the circuits works great
- when i use the zener diode , the +15V becomes deformed (and then my output signal , because i use a offset stage )
i didn't understood this phenomenon !
