Data Sheet

DIGITAL OUTPUT

Figure 59 shows the ADXL355 application circuit with the

recommended bypass capacitors. The communications interface

is either SPI or I2C (see the Serial Communications section for

additional information).

The ADXL355 includes an internal configurable digital band-

pass filter. Both the high-pass and low-pass poles of the filter

are adjustable, as detailed in the Filter Settings Register section

and Table 43. At power-up, the default conditions for the filters

are as follows:

 High-pass filter (HPF) = dc (off)

 Low-pass filter (LPF) = 1000 Hz

 Output data rate = 4000 Hz

AXES OF ACCELERATION SENSITIVITY

Figure 58 shows the axes of acceleration sensitivity. Note that

the output voltage increases when accelerated along the

sensitive axis.
