Hi,
I am confused about current output DAC's,
the one I am looking at requires a negative
voltage reference for making a positive voltage
output (at least from the datasheet schematic)
but I think it should be simpler to just hook it
up with a single supply.
Here is the datasheet page that shows a negative
vref for generating a positive unipolar output:
"http://rocketresearch.nekrom.com/new/current output DAC/currentoutputDACnegativeoutput.jpg"
The datasheet also has a hookup with a positive reference,
but that is then used to generate a negative output:
"http://rocketresearch.nekrom.com/new/current output DAC/currentoutputDACnegativeoutput.jpg"
I think I should just hook it up with a positive reference and
then use a non-inverting amplifier on the output for I to V
conversion:
"http://rocketresearch.nekrom.com/new/current output DAC/single supply current DAC.jpg"
Is that a proper hookup for this?
cheers,
Jamie
