REFCOMP (Pin 4): 4.096V Reference Output. Bypass to
AGND using 10 F tantalum in parallel with 0.1 F ceramic.
AGND (Pin 5): Analog Ground.
EXTCLKIN (Pin 6): External Conversion Clock Input. A 5V
input will enable the internal conversion clock.
SCLK (Pin 7): Data Clock Input.

DGND (Pin 10): Digital Ground.
SHDN (Pin 11): Power Shutdown Input. Low selects
shutdown. Shutdown mode selected by RD. RD = 0V for
Nap mode and RD = 5V for Sleep mode.
RD (Pin 12): Read Input. This enables the output drivers.
RD also sets the shutdown mode when SHDN goes low.
RD and SHDN low selects the quick wake-up Nap mode,
RD high and SHDN low selects Sleep mode.
