AN 009
Getting Started with the KXPS5
Introduction
This application note will help users quickly implement proof-of-concept designs using the I²C or
SPI digital interfaces of the KXPS5 tri-axis accelerometer. Please refer to the KXPS5 Data Sheet
for additional implementation guidelines.
Circuit Schematics
This section shows recommended wiring schematics for the KXPS5 when operating in both I²C
and SPI modes. It also describes an RC method for enabling the KXPS5 upon power up. Please
refer to the KXPS5 Data Sheet for all pin descriptions.
Note: these schematics are recommendations based on proven KXPS5 operation. Your specific
application may require modifications from these recommendations.
