This is SK Lee.
I have a question for AD5754AREZ.
I use +-10.8V mode. (bi-polar)
There is TUE information as below. (TUE means Total Unadjusted Error.)
- A Version +- 0.3 %FSR (+- 10V Range) in data sheet
But I could't find TUE in +-10.8V Range. Output of AD5754AREZ in +-10.8V mode was measured +-10.87V. (I use evaluation board of ADI)I want to know why 0.07V(70mV) difference occurred.
What is the TUE in +-10.8V range ? (0.3 %FSR or 0.5%FSR ?)
I'm currently looking into your query and will get back to you as soon as possible.
The answer I got here was:
"we would expect the part to behave based on our characterization data, which suggests a typical FS error of ~70mV, or ~ 210 LSB on the +/-10.8V range"
