I am designing a model train controller using an LMD18200. One of the outputs from the LMD18200 is a motor current monitor a 377 uA/A signal from the switch FET's.
I can put the proper resistor there to convert the current to a voltage, but what is a good way to convert this pwm signal to a DC voltage that the ADC can read?
The switching will be about 25 - 30 kHz or so.
