Description
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.
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).
Analog Input Channel 0.
AD7682: no connection.
AD7689: Analog Input Channel 1.
AD7682: Analog Input Channel 1.
AD7689: Analog Input Channel 2.
AD7682: no connection.
AD7689: Analog Input Channel 3.
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.
