dhouston, that looks like what i want except that they dont seem to measure below 5A. I do like the fact that they support both AC and DC though. I have 8 outputs that i want to monitor. The max output current ranges from 600mA to 1A and some are AC, some are DC. I want to measure how much current is actually being used even if its less than the output's max rating.

mikeh, ive had a look and it looks like that chip would simply replace a potential divider circuit.

skimask, i take it "voltage divider" is the same as a "potential divider". I remember learning about them in school but so far i dont think ive ever put one together. I think i can see how it would work though. It looks like it would simply lower the voltage to a level suitable for the ADC pin on the pic.

Ive read a wikipedia page about ammeters and it said that you put a resistor in series and measure the voltage accross that resistor and that will tell you how many amps are being drawn through it. This way sounds simple but you said its used *mainly* for DC. Does that mean i can use it on AC? Half of the outputs are AC. What resistor would i use? For the 50V 1A output i assume i need a 50W resistor with the smallest resistance i can find. Rapid sells an OR05 50W Aluminium clad power resistor. It seems a little big but i guess 1A at 50V is a lot for small components.
