Function
IDAC full-scale current adjustment (LSB part). IDAC FS Adj[9:0]
sets the full-scale current of the IDAC. 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.
Set DAC SPI select = 0 to configure DAC 1 path.
Set DAC SPI select = 1 to configure DAC 3 path.
I DAC sleep mode (fast wake-up mode).
IDAC full-scale current adjustment (MSB part)
Set DAC SPI select = 0 to configure DAC 1 path.
Set DAC SPI select = 1 to configure DAC 3 path.
Auxiliary IDAC data (LSB part). AUX IDAC Data[9:0] sets the
magnitude of the aux DAC current. The range is 0 mA to
2 mA, and the step size is 2 µA.
0x000 = 0.000 mA.
0x001 = 0x002 mA.
…
0x3FF = 2.046 mA.
Set DAC SPI select = 0 to configure DAC 1 path.
Set DAC SPI select = 1 to configure DAC 3 path.
Auxiliary IDAC output sign.
0 = positive, current is directed to the AUXx_P pin.
1 = negative, current is directed to the AUXx_N pin.
Auxiliary IDAC current direction.
0 = source.
1 = sink.
Auxiliary IDAC power-down.
Auxiliary IDAC data (MSB part).
Set DAC SPI select = 0 to configure DAC 1 path.
Set DAC SPI select =1 to configure DAC 3 path.
