Hi,
Im trying to convert a 5V PWM output of a microcontroller to a DC signal with a simple RC net. The DC signal are then amplified with an opamp. Please see the attached schematic.
I looking for a way to make the DC signal 0V if the PWM output is constantly 5V (in case of an error). Is there a good solution for this?
Many thanks
