2.5 Interface Specifications

The SGP41 comes in a 6-pin DFN package, see Table 6. Figure 6 shows a typical application circuit. The VDD pin must be

decoupled with an RC element. The required decoupling for VDDH depends on the power supply network connected to the

sensor, a capacitor of 1

F is recommended. VDD and VDDH must be connected to one single supply VDD. The external pull-

pad is electrically connected to GND. Hence, electrical considerations do not impose constraints on the wiring of the die pad.

However, for mechanical stability it is recommended to solder the die pad to the PCB.
