No Internal Connection
Power-Down Control Input. Active high. Contains active pull-down circuit; it may be left
unterminated if not used.
Reference Ground when internal 1.2 V reference used. Connect to AVDD to disable internal reference.
Reference Input/Output. Serves as reference input when internal reference disabled (i.e., tie REFLO
to AVDD). Serves as 1.2 V reference output when internal reference activated (i.e., tie REFLO to AGND).
Requires 0.1
m
F capacitor to AGND when internal reference activated.
Full-Scale Current Output Adjust
No Internal Connection
Analog Common
Complementary DAC Current Output. Full-scale current when all data bits are 0s.
DAC Current Output. Full-scale current when all data bits are 1s.
Reserved. Do Not Connect to Common or Supply.
Analog Supply Voltage (3.3 V)
Selects Input Data Format. Connect to DGND for straight binary, DVDD for two’s complement.
Digital Common
Digital Supply Voltage (3.3 V)
Clock Input. Data latched on positive edge of clock.
