PIN FUNCTION DESCRIPTIONS
Pin No.
Name
Description
1
DB13
Most Significant Data Bit (MSB).
2–13
DB12–DB1 Data Bits 1–12.
14
DB0
Least Significant Data Bit (LSB).
15
SLEEP
Power-Down Control Input. Active High. Contains active pull-down circuit; it may be left unterminated if
not used.
16
REFLO
Reference Ground when Internal 1.2 V Reference Used. Connect to AVDD to disable internal reference.
17
REFIO
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.
18
FS ADJ
Full-Scale Current Output Adjust.
19, 25
NC
No Connect.
20
ACOM
Analog Common.
21
IOUTB
Complementary DAC Current Output. Full-scale current when all data bits are 0s.
22
IOUTA
DAC Current Output. Full-scale current when all data bits are 1s.
23
ICOMP
Internal Bias Node for Switch Driver Circuitry. Decouple to ACOM with 0.1
F capacitor.
24
AVDD
Analog Supply Voltage (+4.5 V to +5.5 V).
26
DCOM
Digital Common.
27
DVDD
Digital Supply Voltage (+2.7 V to +5.5 V).
28
CLOCK
Clock Input. Data latched on positive edge of clock.
