Hi Bob,

I have used PIC microcontrollers quite a lot in the past, they are sometimes a neat way of doing things. I'm not familier enough with the smaller devices to recommend one (I worked with the mid-range family), but I'm sure you can locate a suitable device on their website.

Be aware that the accuracy of the offset will be limited by the resolution of the A/D converter, which will probably be 8 bits, or roughly 20mv per count based on the 5V supply used as the reference voltage.
