Analog ground.
Analog supply (+2.7V to +3.6V).
Clock Iinput.
Connect to digital ground.
Digital supply (+2.7V to +3.6V).
Full scale current adjust. Use a resistor to ground to adjust full scale output current. Full scale output
current = 32 x V
Not internally connected. Recommend no connect.
Compensation pin for internal bias generation. Each pin should be individually decoupled to AGND with
a 0.1 µ F capacitor.
Current outputs of the device. Full scale output current is achieved when all input bits are set to binary 1.
Complementary current outputs of the device. Full scale output current is achieved on the complementary
outputs when all input bits are set to binary 0.
Reference voltage input if Internal reference is disabled. The internal reference is not intended to drive an
external load. Use 0.1 µ F cap to ground when internal reference is enabled.
Connect to analog ground to enable internal 1.2V reference or connect to AV
Connect to digital ground or leave floating for normal operation. Connect to DV
