Application schematics

The device power supply must be provided through the VDD line, a power supply decoupling capacitor (100 nF)

must be placed as near as possible to the supply pins of device (VDD). Depending on the application, an

additional capacitor of 1 µF could be placed on the VDD line to avoid power noise on VDD.

The functionality of the device and the measured data outputs are selectable and accessible through the I²C and

SPI digital interface as shown in the following figures.
