Triaxial, analog acceleration sensor
3.2
Channel multiplexer
On the Ax, Ay, and Az output pin there is always the possibility to grip the continuous analog
output signals of the corresponding axis. Additional to these continuously available signals,
there is the possibility to multiplex any of the 3 axis fully customized to one separate AMUX
output pin via an internal channel multiplexer. This e.g. enables the option to read out all three
axes at only one output pin.
Which of the acceleration signal of the 3 axis is actually multiplexed to the AMUX output pin – or
in which sequence – can be selected through the corresponding SEL.0 and SEL.1 pins of the
sensor module (see chapter 4.3). Do not connect any external capacitor on the AMUX output
pin.
