The digital low-pass filter configuration register has address 0x38 and described in Table 18.
Note: these settings apply only to data output via the unit SPI port and do not affect the low-level
UART output port.
Table 18 Sensor Scaling/Digital Low-Pass Filter Register
Bits
[7:0 ]
The digital low-pass filter register sets the type and cutoff frequency of the filter applied to the
scaled sensor data. The default setting is a 5 Hz Bartlett filter; to switch to a 20 Hz Butterworth
filter, the master sends 0xB840. Figure 10 shows the output response of the different Bartlett
filter settings.
