SDA
Open-Drain Serial Data I/O. Input data is clocked in on the rising edge of SCL,
and output data is clocked out on the falling edge of SCL. External pull-up
resistor required.

SHDN
Shutdown Input. When low, device is in full power-down (FULLPD) mode.
Connect high for normal operation.

REFADJ
Bandgap Voltage-Reference Output/External Adjust Pin. Bypass with a 0.01μF
capacitor to AGND. Connect to V
DD
when using an external reference at REF.

REF
Reference Buffer Output/ADC Reference Input. In internal reference mode, the
reference buffer provides a 4.096V nominal output, externally adjustable at
REFADJ . In external reference mode, disable the internal reference by pulling
REFADJ to V
DD
and applying the external reference to REF.
