Hero999 Banned Mar 3, 2008 #2 You haven't said what voltage range you're after. Is this college work? A resistor will do that. A 1hm: resistor will convert voltages between 0-1V to currents between 0-1:mu:A. The output impedance will also be very high - 1Mhm:. A 10Mhm: resistor will convert voltages from 0 to 10V to 0 to 1:mu:A. Just use Ohm's law.
