I DAC Offset[15:0] is a value added directly to the samples
written to the I DAC.
See Register 0x3C.
Q DAC Offset[15:0] is a value added directly to the samples
written to the Q DAC.
See Register 0x3E.
I DAC FS Adj[9:0] sets the full-scale current of the I DAC.
The full-scale current can be adjusted from 8.64 mA to
31.6 mA in step sizes of approximately 22.5 μA.
0x000 = 8.64 mA.
…
0x200 = 20.14 mA.
…
0x3FF = 31.66 mA.
1 = puts the I-channel DAC into sleep mode (fast
wake-up mode).
See Register 0x40.
I Aux DAC[9:0] sets the magnitude of the auxiliary DAC
current. The range is 0 mA to 2 mA and the step size is 2 μA.
0x000 = 0.000 mA.
0x001 = 0.002 mA.
…
0x3FF = 2.046 mA.
0 = the auxiliary DAC I sign is positive, and the current is
directed to the IOUT1P pin (Pin 67).
1 = the auxiliary DAC I sign is negative, and the current is
directed to the IOUT1N pin (Pin 66).
0 = the auxiliary DAC I sources current.
1 = the auxiliary DAC I sinks current.
I channel auxiliary DAC sleep.
See Register 0x42.
Q DAC FS Adj[9:0] sets the full-scale current of
the I DAC. The full-scale current can be adjusted from
8.64 mA to 31.6 mA in step sizes of approximately 22.5 μA.
0x000 = 8.64 mA.
…
0x200 = 20.14 mA.
…
0x3FF = 31.66 mA.
1 = puts the Q-channel DAC into sleep mode (fast
wake-up mode).
See Register 0x44.
