Hi,
I am driving a PWM circuit and low pass filter from a microcontroller. The output from this circuit will have a voltage in the range of 5-15mV.
However there is a cable (twisted pair with overall screen) between the microcontroller and this PWM circuitry. The cable is around 12-18 inches length.
I'm concerned about noise pick up as I only have a few mV that I am using.
Any help would be appreciated.
Thanks
