Low-side sensing is usually a better way (cheaper, higher performance, etc) unless the device you're monitoring insists on being connected to ground. Analog Devices also makes a couple of good parts (and has a good sampling program): AD628 - Good for 100V CM AD629 - Good for 270V

Hi well one approach is to use one power supply for your OpAmp and ADC. this powersupply should be isolated from the 70V voltage and from other digital circuits you have. well now the ADC will generate the correct value but the 0V and 5V of the ADC output is based on its own GND

If it's DC, Mago, make sure your low voltage and system voltages are referenced to the same low (DC return) potentials. Then stick your current sense resistor in the low line. Another option, with some additional spiff, would be to use an opto-isolator in its linear region to iso
