LSM330DL electrical connections

4.1

External capacitors

The device core is supplied through the Vdd line. Power supply decoupling capacitors

(C4=100

nF ceramic, C3=10 µF 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.
