I've obtained several max4172 SOIC IC's. Could somebody help me get started with the current sense of my 12v source. The mesurable range should be between 0 and 1 amp (lets start with just metering the logic part of my project).

I will be using the 2nd A/D channel on my pic as the first is used to sense battery voltage.

what i need is a schematic with some explanations, the datasheet seems compllicated and doesnt explain how to interface to the pic.

Thanks
