Overview
The ADXL323KCPZ is a small, low power, 2-axis ±3 g iMEMS® accelerometer produced by Analog Devices Inc. This device is designed for cost-sensitive, low power, motion- and tilt-sensing applications. It features a polysilicon surface micromachined sensor and signal conditioning circuitry, providing an open-loop acceleration measurement architecture. The ADXL323KCPZ measures both static acceleration of gravity in tilt-sensing applications and dynamic acceleration resulting from motion, shock, or vibration.
