Help with voltage conversion


Recommended Posts

Hi

I am creating a project with the new arduino due and I need to convert the voltage output (0.55v to 2.75v) from the DAC into a range that is linear from -5v to +5v

I have looked through national semi app note 31 and in the upper right corner of page 6 there is a circuit for voltage conversion but I'm really stuck of where to go from here, I have no idea how to calculate the offset I need and the gain required.

I have an accurate and stable +10v and -10v supply to work with,

Can anyone help? I'd really appreciate any input,

Thanks and regards
