DAC8760: DAC8760 output voltage with ADC input code

Rakesh Patel1
Prodigy 50 points
Part Number: DAC8760

Hi,

 I am trying to configure the DAC8760 with input ADC input code vs output voltage. I have set 0 - 10V as output. 

Is DAC lineally convert the input code (ADC value ) to output voltage or what is the relation between it.

Any help would be appreciated. 

Thanks

Rakesh

    Rakesh,

    If you have the output set to the 0V to 10V range, the conversion equation should be

    Output voltage = [(DAC code)/2^16] *10V

    For example, a DAC code of 0x4CCD converts to

    (0x4CCD/2^16)*10V = (19661d / 65536) * 10V = 3V

    Are you having problems setting the device up or getting the correct output?
