Description
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 adjust[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.
Q aux DAC[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 = 0.002 mA.
…
0x3FF = 2.046 mA.
0 = the auxiliary DAC Q sign is positive, and the current
is directed to the IOUT2P pin (Pin 58).
1 = the auxiliary DAC Q sign is negative, and the current
is directed to the IOUT2N pin (Pin 59).
0 = the auxiliary DAC Q sources current.
1 = the auxiliary DAC Q sinks current.
Q-channel auxiliary DAC sleep
See Register 0x46.
Auxiliary ADC full-scale current.
000 = lowest current.
…
111 = highest current.
Auxiliary ADC reference current.
000 = lowest current.
111 = highest current.
Auxiliary ADC internal capacitor value.
0 = 5 pF.
1 = 10 pF.
Die Temp[15:0] indicates the approximate die
temperature.
0xADCC = −39.9°C.
0xC422 = 25.1°C.
…
0xD8A8 = 84.8°C (see the Temperature Sensor section for
details).
See Register 0x49.
