Hi,
we are looking into using AD5520 ( although we are considering AD5522, both have pros and cons) and there is one information I cannot find in datasheet. Are the MEAS*OUT outputs buffered inside the chip or not? Block schematics seems to suggest there outputs are directly (or via analog switch in case of MEASOUT). Are there any recommendations how close to ADC should be located to the AD5520. I guess my question is if any noise injected on those lines will affect chip performance?
