Accelerometer X, Y, Z Axis ±3g 1.6kHz (X,Y), 550Hz (Z) 16-LFCSP-LQ (4x4) The ADXL335BCPZ-RL7 is a low-power, complete 3-axis accelerometer with analog voltage outputs proportional to acceleration. It measures acceleration along the X, Y, and Z axes with a full-scale range of ±3 g. This device integrates a micro-electromechanical system (MEMS) sensor with signal conditioning circuitry, enabling direct analog output without the need for external amplification. The RL7 suffix indicates tape-and-reel packaging for automated assembly. The ADXL335BCPZ-RL7 is designed for compact, battery-powered, and motion-sensitive applications where low power consumption and ease of integration are critical. Functional Overview The accelerometer operates using a capacitive sensing structure. Acceleration causes displacement of an internal mass, changing capacitance, which is converted into a proportional analog voltage output. Each axis operates independently and provides a continuous analog signal that can be read by a microcontroller’s ADC. External capacitors allow the user to configure bandwidth per axis, enabling optimization for noise or response speed.
