LPS331AP electrical connection

The device core is supplied through the Vdd line. Power supply decoupling capacitors (100

nF ceramic, 10 µF aluminum) should be placed as near as possible to the supply pad of the

device (common design practice).

The functionality of the device and the measured data outputs are selectable and accessible

through the I2C/SPI interface. When using the I2C, CS must be tied high (i.e. connected to

Vdd_IO).
