        Dear forum, I'm designing a board with one ADC AD7997 and one DAC AD5612. I'm going to use REF198 as a voltage reference for AD7997. Could I use the same REF198 to supply the DAC, that use the supply voltage as the reference?

        Hi, Apologies for missing this item. But first if you are using a reference voltage of 4.096V then the analog input voltage range must also be up to 4.096V only. If you provided a voltage beyond this then the result will be full scale. One thing to note …

        Yes you could use the DAC as a reference but you should note the sources of error: VOUT-UNI= D/2^12 x (VREF + VGE) +VZSE + INL where: VOUT-UNI is unipolar mode worst-case output. D is code loaded to DAC. VREF is reference voltage applied to the part …
