PIN FUNCTIONS
BLOCK DIAGRAM
TIMING DIAGRAM
GND (Pin 1): Analog Ground.
VOUT A to VOUT H (Pins 2-5 and 12-15): DAC Analog Volt-
age Output. The output range is 0V to VREF.
REF (Pin 6): Reference Voltage Input. 0V ≤ VREF ≤ VCC.
CA2 (Pin 7): Chip Address Bit 2. Tie this pin to VCC, GND
or leave it oating to select an I2C slave address for the
part (Table 2).
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 to VCC.
SDA (Pin 9): Serial Data Bidirectional Pin. Data is shifted
into the SDA pin and acknowledged by the SDA pin. This
is a high impedance pin while data is shifted in. It is an
open-drain N-channel output during acknowledgment. This
pin requires a pull-up resistor or current source to VCC.
CA1 (Pin 10): Chip Address Bit 1. Tie this pin to VCC, GND
or leave it oating to select an I2C slave address for the
part (Table 2).
CA0 (Pin 11): Chip Address Bit 0. Tie this pin to VCC, GND
or leave it oating to select an I2C slave address for the
part (Table 2).
VCC (Pin 16): Supply Voltage Input. 2.7V ≤ VCC ≤ 5.5V.
