Description
14 SDO SDO DO
Serial Data Output. The conversion result is output on this pin, synchronized to SCK. In
unipolar modes, conversion results are straight binary; in bipolar modes, conversion
results are twos complement.
15 VIO VIO P
Input/Output Interface Digital Power. Nominally at the same supply as the host interface
(1.8 V, 2.5 V, 3 V, or 5 V).
16 IN0 IN0 AI Analog Input Channel 0.
