I am hooking up a 12bit current output DAC (DAC7811)
with a 0V to 5V output voltage range.
I am putting an opamp I to V converter on the output of this current output DAC.
The datasheet shows these two hookups:
- negative voltage output Vout = -Vref * Code/4096
- positive voltage output
I would like the positive voltage output but it requires a -2.5V reference. What would be the best way to hook this DAC up for a 0V to 5V output range?
If I use a a -5V reference instead of the -2.5V reference will this provide a 0V to 5V output range? Does the output opamp need a bipolar supply as well for this?
