Other Parts Discussed in Thread: ADS8482
We have a design with the ADS8472IBRGZT in 8 bit mode using BYTE to toggle the output of DB15:DB8 between high and low bytes. When we assert BYTE high we are always getting bits 9 & 8 as ones. The data sheet on page 24 Table 2 indicates that DB15:DB8 should be outputting D7-D0. What we see is D1,D0 both ones. On page 8 TERMINAL FUNCTIONS, BYTE Select input talks about low byte D[9:2] of the 16 most significant bits is folded back to the high byte of the 16 most significant pins SB[17:0]. This makes absolutely no since the the ADS8472 is a 16 bit part pin-out diagram ; the table on page 8 shows DB0-DB15. Clearly there is something fundamental wrong with the data sheet and/or part functionality. Anyone have any clue about this?
