Overview
The ADXL335BCPZ-RL7 is a small, low power, complete 3-axis ±3 g accelerometer produced by Analog Devices Inc. This MEMS (Micro-Electro-Mechanical Systems) sensor is designed to measure acceleration in the X, Y, and Z axes, providing signal conditioned voltage outputs. It operates within a supply voltage range of 1.8 V to 3.6 V and is housed in a 16-lead LFCSP (Lead Frame Chip Scale Package) with a compact footprint of 4 mm × 4 mm × 1.45 mm. The device is notable for its low power consumption, excellent temperature stability, and the ability to survive 10,000 g shocks, making it suitable for a wide range of applications.
