Step 2: Initialize DSP
As the D/A-READOUT register value depends on the settings of SENSITIVITY,
VOQ and CLAMP-LOW/HIGH, these registers have to be initialized with defined val-
ues, first:
– VOQ_INITIAL = 2.5 V
– Clamp-Low = 0 V
– Clamp-High = 4.999 V
– Sens_INITIAL (see table 3-1.)
Table 3–1:

0.39
1 kHz
0.42

0.83
Step 3: Define Calibration Points
The calibration points 1 and 2 can be set inside the specified range. The corresponding
values for V_OUT1 and V_OUT2 result from the application requirements.
Lowclampingvoltage  V_OUT1,2  Highclampingvoltage
For highest accuracy of the sensor, calibration points near the minimum and maximum
input signal are recommended. The difference of the output voltage between calibration
point 1 and calibration point 2 should be more than 3.5 V.
