DD
or GND to set the device address.
3 4 A0 Address Select 0. Connect to V
DD
or GND to set the device address.
4 — REFH1 DAC1 High Reference Input. REFH1 must be equal to or greater than REFL1.
5 — REFL1 DAC1 Low Reference Input. REFL1 must be equal to or less than REFH1.
6 6 OUT1 DAC1 Output. OUT1 is buffered with a unity-gain amplifier.
7 — REFH2 DAC2 High Reference Input. REFH2 must be equal to or greater than REFL2.
8 — REFL2 DAC2 Low Reference Input. REFL2 must be equal to or less than REFH2.
9 7 OUT2 DAC2 Output. OUT2 is buffered with a unity-gain amplifier.
10 8 GND Ground
11 10 OUT3 DAC3 Output. OUT3 is buffered with a unity-gain amplifier.
12 — REFL3 DAC3 Low Reference Input. REFL3 must be equal to or less than REFH3.
13 — REFH3 DAC3 High Reference Input. REFH3 must be equal to or greater than REFL3.
14 11 OUT0 DAC0 Output. OUT0 is buffered with a unity-gain amplifier.
15 — REFL0 DAC0 Low Reference Input. REFL0 must be equal to or less than REFH0.

17 14 SCL Serial-Clock Input. Connect SCL to V
DD
through a 2.4kΩ pullup resistor.
18 15 V
DD
Positive-Power Input. Connect V
DD
to a +2.7 to +5.25V power supply. Bypass V
DD
to GND with a 0.1µF
capacitor as close to the device as possible.
19 16 SDA Serial Data Input/Output. Connect SDA to V
DD
through a 2.4kΩ pullup resistor.
20 1 A3 Address Select 3. Connect to V
DD
or GND to set the device address.
— 5 N.C. No Connection. Not internally connected.
—9 MUTE
Active-Low Mute Input. Connect MUTE low to drive all DAC outputs to their respective reference low
voltages. Connect MUTE to V
DD
for normal operation.
— 12 REFL DAC Low Reference Input. REFL must be equal to or less than REFH.
— 13 REFH DAC High Reference Input. REFH must be equal to or greater than REFL.
