Hello all,
I need to convert a 3.3 VDC PWM signal (PWM freaquency adjustable if needed, but not duty cycle) to an anolog output of 5 to 1 VDC (PWM max duty cycle = 1 VDC, Min duty cycle = 5 VDC).
I don't want to add a micro controller to do this, but my op amp skills have not been used since in school.
I've a got a non-inverting op amp circuit with a RC low pass filter made that converts the PWM to a 0 to 5 VDC analog(PWM minduty cycle = 0 VDC, Max duty cycle = 5 VDC).
My question: How do I convert this 0 - 5VDC analog signal to a 5VDC - 1VDC signal?
Any help greatly appreciated!:grin:
