Digital Data Bit 9, the Most Significant Bit through Digital Data Bit 0, the Least Significant Bit, of the
Q Channel.
Digital Data Bit 9, 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 20 A 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 0.1 F 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
For use in reducing bandwidth/noise of I Channel. Recommended: connect 0.1 F to AV
For use in reducing bandwidth/noise of Q Channel. Recommended: connect 0.1 F to AV
Analog Ground Connections.
The complimentary current output of the I Channel. Bits set to all 0’s gives full scale current.
Current output of the I Channel. Bits set to all 1’s gives full scale current.
The complimentary current output of the Q Channel. Bits set to all 0’s gives full scale current.
Current output of the Q Channel. Bits set to all 1’s gives full scale current.
No Connect. Recommended: connect to ground.
Analog Supply (+2.7V to +5.5V).
Digital Ground.
