REF
(Pin 3): 2.50V Reference Output. Bypass to AGND
with 1µF.
REFCOMP (Pin 4): 4.096V Reference Output. Bypass to
AGND using 10µF tantalum in parallel with 0.1µF 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.
CLKOUT (Pin 8): Conversion Clock Output.
D
OUT
(Pin 9): Serial Data Output.
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.
