BASIC CONNECTIONS
Pinout Description
Figure 4. Accelerometer with Recommended
Connection Diagram
Figure 5. Recommended PCB Layout for Interfacing
Accelerometer to Microcontroller
NOTES:
Use a 0.1
μ
F capacitor on VDD to decouple the power
source.
Physical coupling distance of the accelerometer to the
microcontroller should be minimal.
Place a ground plane beneath the accelerometer to reduce
noise, the ground plane should be attached to all of the open
ended terminals shown in Figure 5.
Use an RC filter of 1 k
and 0.01
μ
F on the output of the
accelerometer 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/D sampling rate and any external power supply switching
frequency should be selected such that they do not interfere
with the internal accelerometer sampling frequency. This
will prevent aliasing errors.
