Use a 0.1 μF and a 10 μF capacitor on AV
Physical coupling distance of the accelerometer to the microcontroller should be minimal.
PCB layout of power and ground should not couple power supply noise.
Accelerometer and microcontroller should not be a high current path.
Any external power supply switching frequency should be selected such that they do not interfere with the internal
accelerometer sampling frequency (sampling frequency). This will prevent aliasing errors.
Physical distance of the two GND pins (Pin 2 and Pin 5) tied together should be at the shortest distance.
