sorry for again troubling you....but i have a query regarding the REFIO pin in the Chip ADS8558 so i thought of continuing in this thread only....i am using the internal reference and so i have enabled the REFen/WR pin but in this case the range mentioned on the REFIO pin is 0.5 volts to 3.025v. Is it possible to check what voltage am getting on the REFIO pin?? as in i saw the voltage on multimeter and it showed me 4 volts. Am i doing anything wrong here??? i am getting the output on the parallel data bus but not very accurate...and i know that the output data has direct relation with the reference.
