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 maxim adjustable sink

current setting.

AVDD

Supply

High-Voltage Analog Supply. Bypass to GND with 0.1µF capacitor.
