PIN FUNCTIONS

VDD (Pin 3): Input Supply. Bypass this pin to GND with a

capacitor (0.1µF to 1µF).

IDAC (Pin 6): Bidirectional Current DAC Output.

EN (Pin 7): Chip Enable Pin. Current DAC output is in

Hi-Z state when EN is Grounded. Do not leave EN floating.

SDA (Pin 1): Serial Bus Data Input and Open-Drain Output.

A pull-up resistor to VDD is required in the application.

SCL (Pin 2): Serial Bus Clock Input.

GPO (Pin 8): Open-Drain Digital Output. A pull-up resistor

to VDD is required.

ALERT (Pin 4): Open-Drain Digital Output. A pull-up

resistor to VDD is required.

ASEL1/ASEL0 (Pins 10, 9): Serial Bus Address Select

Inputs. Each pin has three states (VDD, FLOATING and

GND); these two pins provide 9 addresses.

GND (Pin 5): Ground.
