Figure 4. LIS3L02DQ Electrical Connection
The device core is supplied through Vdd line (Vdd typ=3.3V) while the I/O pads are supplied through
Vdd_IO. Power supply decoupling capacitors (100 nF ceramic, 10 µF Al) should be placed as near as pos-
sible to 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 Fig 4).The functionality of the device and the mea-
sured acceleration data is selectable and accessible through the I
CS must be tied high while SDO must be left floating.
5.1 Soldering Information
The QFN-44 package is lead free and green package qualified for soldering heat resistance according to
JEDEC J-STD-020D. Land pattern and soldering recommendations are available upon request.
