I need to measure the current in a electrolysis process.
Range from 0 to 500mA only
.1mA resolution is required. I plan to use a shunt resistor and use a 14 bit adc,(Please suggest a ADC also. need low cost,because my equipment uses 9 channels like this .
Also I need to cut off the line if current exceeds a preset value. Could you suggest a suitable logic level MOSFET for the purpose?
Any guidelines for me? Sample designs or app notes?
Thanks
