TYPE PULL U/D
FUNCTION
OUT Output
Adjustable Sink Current Output Pin. The current sinks into the OUT pin is equal to the DAC setting times the
maximum adjustable sink current divided by 128. See SET pin function description for the maximum adjustable
sink current setting.
AVDD Supply
High-Voltage Analog Supply. Bypass to GND with 0.1µF capacitor.
WP
Input Pull-Down Write Protect. Active Low. To enable programming, connect to 0.7*VDD supply or greater.
GND Supply
Ground connection.

In/Out
Input
System power supply input. Bypass to GND with 0.1µF capacitor.
I²C Serial Data Input
I²C Clock Input
SET Analog
Maximum Sink Current Adjustment Point. Connect a resistor from SET to GND to set the maximum adjustable
sink current of the OUT pin. The maximum adjustable sink current is equal to (AVDD/20) divided by RSET.
