 Hi,I'm using cy68013-56pvxc on my circuit  board with a MAXIM1316 analog-digital chip.I separate the AGND and DGND net and connect them together with a 0 ohm resisitor.recently i have received my circuit board and have check it that everything is ok.But After I welded cy68013-56pvxc on board (no other component on board)i found that the AGND and DGND was connected.I check the single chip and the board carefully and nothing is wrong except that pin 13 and pin 17 were not internally connected(the datasheet declares that these two pins are all AGND pins).My circuit is attached below.Please help me.
