STATUS
NOTES:
Use a 0.1
μ
F capacitor on V
DD
to decouple the power
source.
Physical coupling distance of the accelerometer to the mi-
crocontroller should be minimal.
Placeagroundplanebeneaththeaccelerometertoreduce
noise, the ground plane should be attached to all internal
V
SS
terminals shown in Figure 4.
Use an RCfilter of1 k
and 0.1
μ
F onthe outputof theac-
celerometer to minimize clock noise (from the switched
capacitor filter circuit).
PCB layout of power and ground should not couple power
supply noise.
Accelerometer and microcontroller should not be a high
current path.
A/Dsamplingrateandanyexternalpowersupplyswitching
frequency should be selected such that they do not inter-
fere with the internal accelerometer sampling frequency.
This will prevent aliasing errors.
