2.5 Interface Specifications
The SGP40 comes in a 6-pin DFN package, see Table 6. Figure 5 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-up resistors
(e.g., Rp = 10 k) are required to pull the SDA and SCL signal lines high. For dimensioning resistor sizes please take bus
capacity and communication frequency into account (see section 7.1 of NXPs I2C Manual for more details, see footnote 9 on
page 5). It should be noted that pull-up resistors may be included in I/O circuits of microcontrollers. The die pad or center 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.
