Serial Clock Input
Address Select Inputs
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.
Shutdown Input. When low, device is in full power-down (FULLPD) mode.
Connect high for normal operation.

Bandgap Voltage-Reference Output/External Adjust Pin. Bypass with a 0.01µF
capacitor to AGND. Connect to V
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.
