I voltage reference might help you out.
Take a look at my testing breadboard at :
https://sites.google.com/site/olewsaa/ya...all-sensor
(the section : Using a 10 bit (low precision) MCP3008 analog to digital converter in differential mode and a WCS1800 35A current sensor.).
These voltage references are very cheap and quite accurate. 190 ohms are fairly lowso you'll need a resistor ladder to suit your analog input range.
