LTC2609/LTC2619/LTC2629
PIN
GND (Pin 1): Analog Ground.
REFLO (Pin 2): Reference Low. The voltage at this pin sets
the zero scale (ZS) voltage of all DACs. This pin can be
raised up to 1V above ground at V
ground at V
REFA to REFD (Pins 3, 6, 12, 15): Reference Voltage
Inputs for each DAC. REFx sets the full-scale voltage of the
DACs. REFLO ≤ REFx ≤ V
V
Outputs. The output range is from REFLO to REFx.
CA2 (Pin 7): Chip Address Bit 2. Tie this pin to V
or leave it floating to select an I
(Table 1).
SCL (Pin 8): 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

SDA (Pin 9): Serial Data Bidirectional Pin. Data is shifted
into the SDA pin and acknowledged by the SDA pin. This
pin is high impedance pin while data is shifted in and is an
open-drain N-channel output during acknowledgment.
SDA requires a pull-up resistor or current source to V
CA1 (Pin 10): Chip Address Bit 1. Tie this pin to V
or leave it floating to select an I
(Table 1).
CA0 (Pin 11): Chip Address Bit 0. Tie this pin to V
