See Section 3: Application information on page 12.
1. See SET pin function in this table for the maximum adjustable sink current setting.
AV
DD
Supply
High-voltage analog supply.
Bypass to GND with a 0.1 µF capacitor.
WP Input
WRITE protectection.
Active-low. To enable write operations to the DAC or to the EEPROM
writing, connect to 0.7 V
DD
or greater. Internally pulled down by a 130 kΩ
resistor.
GND Supply ground.
V
DD
Supply
System power supply input.
Bypass to GND with a 0.1 µF capacitor.
SDA Input/Output I
2
C serial data input/output.
SCL Input I
2
C serial 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
