NAME
FUNCTION
1
A3
Address Select 3. Connect to VDD or GND to set the device address.
2
A2
Address Select 2. Connect to VDD or GND to set the device address.
3
A1
Address Select 1. Connect to VDD or GND to set the device address.
4
A0
Address Select 0. Connect to VDD or GND to set the device address.
5
REFH1
DAC1 High Reference Input. REFH1 must be equal to or greater than REFL1.
6
REFL1
DAC1 Low Reference Input. REFL1 must be equal to or less than REFH1.
7
OUT1
DAC1 Output. OUT1 is buffered with a unity-gain amplifier.
8
GND
Ground
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.
10
N.C.
No Connection. Not internally connected.
11
OUT0
DAC0 Output. OUT0 is buffered with a unity-gain amplifier.
12
REFL0
DAC0 Low Reference Input. REFL0 must be equal to or less than REFH0.
13
REFH0
DAC0 High Reference Input. REFH0 must be equal to or greater than REFL0.
14
SCL
Serial Clock Input. Connect SCL to VDD through a 2.4k
pullup resistor.
15
VDD
Positive Power Input. Connect VDD to a +2.7 to +5.25V power supply. Bypass VDD to GND with a 0.1F
capacitor as close to the device as possible.
16
SDA
Serial Data Input/Output. Connect SDA to VDD through a 2.4k
pullup resistor.
Typical Operating Characteristics (continued)
(VDD = +3V, VREFH_ = +3V, VREFL_ = GND, RL = 5k
, CL = 100pF, TA = +25°C, unless otherwise noted.)
