NOTE:
A 0.1
μF
ceramic capacitor can be placed connecting pin 3 (AVDD) to pin 4 (AVSS). In addition, another 0.1
μF
ceramic capacitor can be place connecting pin 9 (DVDD) to pin 8 (DVSS). The capacitors should be placed close
to the pins of the MMA7660FC and is recommended for testing and to adequately decouple the accelerometer
from noise on the power supply.
