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.

Pad (EPAD)
NC
The exposed pad is not connected internally. For increased reliability of the solder joints,
it is recommended that the pad be soldered to the system ground plane.
1AI = analog input, AI/O = analog input/output, DI = digital input, DO = digital output, P = power, NC = no internal connection.
