4.1
External capacitors
The device core is supplied through the Vdd line. Power supply decoupling capacitors
(C4=100
nF ceramic, C3=10 F Al) should be placed as near as possible to the supply pin
of the device (common design practice).
All the voltage and ground supplies must be present at the same time to have proper
behavior of the IC (refer to
Figure 5).
The functionality of the device and the measured acceleration/angular rate data is
selectable and accessible through the SPI/I2C interface.
