The functional block diagram as well as figs.4 and 5 of the data sheet for the AD7547 shows AGND on pin 1, however the LCCC and PLCC packages show pin 1 as NC and pin 2 as AGND. Which is correct?
Both are correct. The package being used in the block diagram is for the DIP/SOIC packages only. Although the internal blocks of the LCCC and PLCC are the same with the DIP and SOIC packages, they differ only in pinouts.
Hope this answers your question.
I am moving the thread to the Precision DAC community. Someone here will respond to your inquiry.
