Pin Descriptions
PIN NO.
PIN NAME
DESCRIPTION
1-10
D9 (MSB) Through Digital Data Bit 9, (Most Significant Bit) through Digital Data Bit 0, (Least Significant Bit).
D0 (LSB)
15
SLEEP
Control Pin for Power-Down mode. Sleep Mode is active high; Connect to ground for Normal Mode. Sleep
pin has internal 20µA active pulldown current.
16
REFLO
Connect to analog ground to enable internal 1.2V reference or connect to AV_DD to disable internal
reference.
17
REFIO
Reference voltage input if internal reference is disabled. Reference voltage output if internal reference is
enabled. Use 0.1µF cap to ground when internal reference is enabled.
18
19, 25
FSADJ
NC
Full Scale Current Adjust. Use a resistor to ground to adjust full scale output current. Full Scale Output
Current = 32 x V_FSADJ/R_SET.
No Connect. These should be grounded, but can be left disconnected.
21
IOUTB
The complementary current output of the device. Full scale output current is achieved when all input bits
are set to binary 0.
22
IOUTA
Current output of the device. Full scale output current is achieved when all input bits are set to binary 1.
23
COMP
Connect 0.1µF capacitor to ACOM.
24
AV_DD
Analog Supply (+3.0V to +3.6V).
20
ACOM
Connect to Analog Ground.
26, 11-14
DCOM
Connect to Digital Ground.
27
DV_DD
Digital Supply (+3.0V to +3.6V).
28
CLK
Clock Input.
