Description
Most Significant Data Bit (MSB).
Data Bits 1–8.
Least Significant Data Bit (LSB).
No Internal Connection.
Power-Down Control Input. Active High. Contains active pull-down circuit, thus 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
ACOM). Requires 0.1 F capacitor to ACOM when internal reference activated.
Full-Scale Current Output Adjust.
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.
Internal Bias Node for Switch Driver Circuitry. Decouple to ACOM with 0.1 F capacitor.
Analog Supply Voltage (+4.5 V to +5.5 V).
Digital Common.
Digital Supply Voltage (+2.7 V to +5.5 V).
Clock Input. Data latched on positive edge of clock.
