I have outdated datasheet for LMP91200 and samples from the same time. I designed circuit to measure temperature and pH with ADC connected to LMP91200 using internal analog switches, according to this internal schematic:
Can I use new revisions of the LMP91200 the same way, or has the internal circuit changed?
on page 2 of the device datasheet there is the Revision History, showing that the SPI function has been removed/disabled from Rev.D to Rev.E
refer to (or compare) the Typical Application diagram on page 1 of the 2 revisions to see it properly (I attached it here for simplicity).
hope this helped a bit
