ADS7863
SBAS383–JUNE 2007
Output data consist of a channel indicator ('0' for
CHx0 or '1' for CHx1), followed by a '0', 12 bits of
conversion results, and another '00'.
With M0 set to '1' and M1 = 0, the ADS7863
automatically cycles between the multiplexer inputs
(ignoring the SDI pin) while offering the conversion
result of CHAx on SDOA and the conversion result of
CHBx on SDOB (see
Figure 18
).
