+ AIN (Pin 1): Positive Analog Input, ±2.5V.
– AIN (Pin 2): Negative Analog Input, ±2.5V.
VREF (Pin 3): 2.50V Reference Output.
REFCOMP (Pin 4): 4.06V Reference Output. Bypass to
AGND using 10µF tantalum in parallel with 0.1µF or
10µF ceramic.
AGND (Pin 5): Analog Ground.
D11 to D4 (Pins 6 to 13): Three-State Data Outputs.
DGND (Pin 14): Digital Ground for Internal Logic. Tie to
AGND.

D3 to D0 (Pins 15 to 18): Three-State Data Outputs.
OGND (Pin 19): Digital Ground for Output Drivers. Tie
to AGND.
NAP/SLP (Pin 20): Power Shutdown Mode. Selects the
mode invoked by the SHDN pin. Low selects Sleep
mode and high selects quick wake-up Nap mode.
SHDN (Pin 21): Power Shutdown Input. A low logic
level will invoke the Shutdown mode selected by the
NAP/SLP pin.
RD (Pin 22): Read Input. This enables the output
drivers when CS is low.
