Figure 21: Pin-out of the BMA150 (bottom view);
Note: The pin-out schemes of the BMA150 and the SMB380 in QFN package are identical.
Table 12: Pin-out description of the BMA150
Recommendation for decoupling: between GND and VDD (pin 1 or 2) a 22nF capacitor and between
GND and IOVDD (pin 9) a 100nF capacitor should be connected.
