ADXL335BCPZ
Accelerometer X, Y, Z Axis ±3g 1.6kHz (X,Y), 550Hz (Z) 16-LFCSP-LQ (4x4) The ADXL335BCPZ is a small, thin, low-power, complete 3-axis accelerometer with signal-conditioned voltage outputs. It measures acceleration with a minimum full-scale range of ±3 g. The device outputs analog voltages proportional to acceleration in each of the three orthogonal axes (X, Y, and Z). The accelerometer is designed for low power consumption and high resolution, making it suitable for mobile devices, tilt sensing, motion detection, and vibration monitoring. It operates over a wide temperature range and requires minimal external components, enabling easy integration into compact systems. Functional Overview The ADXL335 uses a capacitive sensing structure to detect acceleration. Changes in acceleration result in differential capacitance changes, which are converted into voltage outputs through an internal signal conditioning circuit. Each axis provides an independent analog output that can be directly interfaced with ADC inputs of microcontrollers or other processing units. Bandwidth for each axis can be adjusted using external capacitors, allowing flexibility depending on application requirements.
