Pin Description

NAME

FUNCTION

Address Select 2. Connect to VDD or GND to set the device address.

Address Select 1. Connect to VDD or GND to set the device address.

Address Select 0. Connect to VDD or GND to set the device address.

—

REFH1

DAC1 High Reference Input. REFH1 must be equal to or greater than REFL1.

—

REFL1

DAC1 Low Reference Input. REFL1 must be equal to or less than REFH1.

OUT1

DAC1 Output. OUT1 is buffered with a unity-gain amplifier.

—

REFH2

DAC2 High Reference Input. REFH2 must be equal to or greater than REFL2.

—

REFL2

DAC2 Low Reference Input. REFL2 must be equal to or less than REFH2.

OUT2

DAC2 Output. OUT2 is buffered with a unity-gain amplifier.

GND

Ground

OUT3

DAC3 Output. OUT3 is buffered with a unity-gain amplifier.

—

REFL3

DAC3 Low Reference Input. REFL3 must be equal to or less than REFH3.

—

REFH3

DAC3 High Reference Input. REFH3 must be equal to or greater than REFL3.

OUT0

DAC0 Output. OUT0 is buffered with a unity-gain amplifier.

—

REFL0

DAC0 Low Reference Input. REFL0 must be equal to or less than REFH0.

—

REFH0

DAC0 High Reference Input. REFH0 must be equal to or greater than REFL0.

SCL

Serial-Clock Input. Connect SCL to VDD through a 2.4k

Ω pullup resistor.

VDD

Positive-Power Input. Connect VDD to a +2.7 to +5.25V power supply. Bypass VDD to GND with a 0.1µF

capacitor as close to the device as possible.

SDA

Serial Data Input/Output. Connect SDA to VDD through a 2.4k

Ω pullup resistor.

Address Select 3. Connect to VDD or GND to set the device address.

—

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 VDD for normal operation.

—

REFL

DAC Low Reference Input. REFL must be equal to or less than REFH.

—

REFH

DAC High Reference Input. REFH must be equal to or greater than REFL.

Typical Operating Characteristics (continued)

(VDD = +3V, VREFH_ = +3V, VREFL_ = GND, RL = 5k

Ω, CL = 100pF, TA = +25°C, unless otherwise noted.)
