Application hints

Figure 14. LPS22HB electrical connections (top view)

The device power supply must be provided through the VDD line; a power supply

decoupling capacitor C1 (100 nF) must be placed as near as possible to the supply pads of

the device. Depending on the application, an additional capacitor of 4.7 μF could be placed

on VDD line.

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 to Vdd_IO.

All the voltage and ground supplies must be present at the same time to have proper

behavior of the IC (refer to Figure 14). It is possible to remove VDD while maintaining

Vdd_IO without blocking the communication bus, in this condition the measurement chain is

powered off.
