PIN NAME
DESCRIPTION
D11 (MSB) Through Digital data Bit 11, (Most Significant Bit) through Digital Data Bit 0, (Least Significant Bit).
D0 (LSB)
SLEEP
Control pin for power-down mode. Sleep Mode is active high; Connect to ground for Normal Mode. Sleep pin has
internal 20µA active pull-down current.
REFLO
REFIO
Connect to analog ground to enable internal 1.2V reference or connect to AV_DD to disable internal reference.
Reference voltage input if internal reference is disabled. Reference voltage output if internal reference is enabled.
Use 0.1µF capacitor to ground when internal reference is enabled.
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.
IOUTB
The complementary current output of the device. Full scale output current is achieved when all input bits are set
to binary 0.
IOUTA
Current output of the device. Full scale output current is achieved when all input bits are set to binary 1.
COMP
Connect 0.1µF capacitor to ACOM.
AV_DD
ACOM
Analog supply (+3.0V to +3.6V).
Connect to analog ground.
DCOM
Connect to digital ground.
DV_DD
CLK
Digital supply (+3.0V to +3.6V).
Clock input.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
2. For Moisture Sensitivity Level (MSL), please see product information page for ISL5857. For more information on MSL, please see tech brief TB363.
