Possibility of using the PWM output as a proportional DC output??
Craig Lee email (remove spam text)
I am attempting to use the PWM output on a '73A through a
capacitor to ground to get a proportional DC voltage out.
The PWM frequency is 3090 Hz and the duty cycle is varied.
However, I get too much ripple on the DC output.
Any brilliant ideas? Is my frequency too low? Too high? How
do I select the proper capacitor? Do I need a diode?
