But idea would still be practical with 16 bit or 24 bit R2R. Only less outputs 'd be availableYup, that's the whole problem. That's why I want to do something in analog-domain. ;-)
VREFA and VREFB are DAC voltage reference inputs.The analog signal on these pins is utilized to set the ref-erence voltage on the string DAC. The input signal canrange from AVSS to VDD.
