Digital Data Bit 11, (Most Significant Bit) through Digital Data Bit 0, (Least Significant Bit).
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.
Connect to analog ground to enable internal 1.2V reference or connect to AV
reference.
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.
Full Scale Current Adjust. Use a resistor to ground to adjust full scale output current. Full Scale Output
Current = 32 x V
No Connect. These should be grounded, but can be left disconnected.
The complementary current output of the device. Full scale output current is achieved when all input bits
are set to binary 0.
Current output of the device. Full scale output current is achieved when all input bits are set to binary 1.
Connect 0.1µF capacitor to ACOM.
Analog Supply (+3.0V to +3.6V).
Connect to Analog Ground.
Connect to Digital Ground.
Digital Supply (+3.0V to +3.6V).
