Description
Most Significant Data Bit (MSB).
Least Significant Data Bit (LSB).
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 ACOM).
Requires 0.1 F capacitor to ACOM when internal reference activated.
Full-Scale Current Output Adjust.
Bandwidth/Noise Reduction Node. Add 0.1 F to AVDD for optimum performance.
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 (+2.7 V to +5.5 V).
No Internal Connection.
Digital Common.
Digital Supply Voltage (+2.7 V to +5.5 V).
Clock Input. Data latched on positive edge of clock.
