Pin names and functions

Name

Type

Function

OUT

Analog

Adjustable sink current output pin. (1)

See Section 3: Application information on page 11.

See SET pin function in this table for the maximum adjustable sink current setting.

AVDD

Supply

High-voltage analog supply.

Bypass to GND with a 0.1µF capacitor.

Input

WRITE protectection.

Active-low. To enable write operations to the DAC or to the EEPROM

writing, connect to 0.7VDD or greater. Internally pulled down by a 130kΩ

resistor.

GND

Supply ground.

VDD

Supply

System power supply input.

Bypass to GND with a 0.1µF capacitor.

SDA

In/Out

I2C serial data input/output.

SCL

Input

I2C 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

AVDD /20 divided by RSET (see Figure 4 on page 6).
