TYPICAL PERFOR A CE CHARACTERISTICS
UW
VDD Supply Current vs
Temperature (Unipolar Mode)
AIN+ (Pin 1): Positive Analog Input.
AIN– (Pin 2): Negative Analog Input.
VREF (Pin 3): 2.50V Reference Output. Bypass to AGND
with 1
F.
REFCOMP (Pin 4): 4.096V Reference Output. Bypass to
AGND using 10
F tantalum in parallel with 0.1F 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.
DOUT (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.
