CA0 (Pin 1):
Chip Address Bit 0. Tie this pin to V
CC
, GND
or leave it floating to select an I
2
C slave address for the
part (Table 1).
CA1 (Pin 2):
Chip Address Bit 1. Tie this pin to V
CC
, GND
or leave it floating to select an I
2
C slave address for the
part (Table 1).
LDAC (Pin 3):
Asynchronous DAC Update. A falling edge
of this input after four bytes have been written into the part
immediately updates the DAC register with the contents of
the input register. A low on this input without a complete
32-bit (four bytes including the slave address) data write
transfer to the part wakes up sleeping DACs without
updating the DAC output. Software power-down is dis-
abled when LDAC is low. LDAC is disabled when tied high.
SCL (Pin 4):
Serial Clock Input Pin. Data is shifted into the
SDA pin at the rising edges of the clock. This high
impedance pin requires a pull-up resistor or current source
to V
CC
.
SDA (Pin 5):
Serial Data Bidirectional Pin. Data is shifted
into the SDA pin and acknowledged by the SDA pin. This
pin is high impedance while data is shifted in and an open-
drain N-channel output during acknowledgment. Requires
a pull-up resistor or current source to V
CC.
CA2 (Pin 6):
Chip Address Bit 2. Tie this pin to V
CC
, GND
or leave it floating to select an I
2
C slave address for the
part (Table 1).

GND (Pin 10):
Analog Ground
.
REFLO (Pin 11):
Reference Low. The voltage at this pin
sets the zero scale (ZS) voltage of all DACs. The V
REFLO
pin
can be used at voltages up to 1V for V
CC
= 5V, or 100mV
for V
CC
= 3V.

OUTA
(Pin 12):

Exposed Pad (Pin 13):
Ground. Must be soldered to
PCB ground.
