I have a Pic 16F88 controlling a half bridge with a 8khz PWM. It works correctly. I am trying to add some current limiting to this controller. I have installed a ..005 ohm resistor from the low side mosfet source to ground, and I measure the voltage across the resistor. All Ok . My Question is what do I have to do to this signal to make it acceptable to
Pic ADC or the comparators. The software for the adc & comparators I can Handle, it is the signal conditioning that has me stumped.

Your help is greatly appreciated.
