Digital Data Bit 7, the Most Significant Bit through Digital Data Bit 0, the Least Significant Bit, of the Q
channel.
Digital Data Bit 7, the Most Significant Bit through Digital Data Bit 0, the Least Significant Bit, of the I
channel.
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 voltage input if internal reference is disabled and 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 Per Channel = 32 x I
Reduces noise. Connect each to AV
tied together externally.
Analog Ground Connections.
The complementary current output of the I channel. Bits set to all 0s gives full scale current.
Current output of the I channel. Bits set to all 1s gives full scale current.
The complementary current output of the Q channel. Bits set to all 0s gives full scale current.
Current output of the Q channel. Bits set to all 1s gives full scale current.
No Connect. Recommended: Connect to ground.
Analog Supply (+2.7V to +5.5V).
Digital Ground.
Supply voltage for digital circuitry (+2.7V to +5.5V).
