ADXL355BEZ-RL7 ADXL355BEZ-RL7

This is a high-precision three-axis digital MEMS accelerometer manufactured by Analog Devices, featuring ultra-low noise, tiny zero-g offset drift and sealed packaging for excellent long-term stability, dedicated to high-precision vibration detection, tilt measurement and inertial attitude calculation scenarios.

ADXL355 refers to the core model of high-stability digital triaxial acceleration sensor series. BEZ stands for hermetically sealed industrial grade LCC packaging version. RL7 denotes small-quantity tape-and-reel packaging specification for automated SMT production assembly.

Three programmable acceleration measuring ranges are optional: ±2g, ±4g, ±8g, matched with 20-bit high-resolution ADC digital output, the sensitivity value changes adaptively with different ranges. Ultra-low noise density reaches 22.5μg/√Hz, zero offset temperature drift is controlled within 0.15mg/℃, greatly reducing regular calibration frequency for long-term running equipment.

Dual digital communication interfaces including SPI and I2C are integrated, supporting synchronous multi-chip sampling and digital programmable high/low pass filters inside the chip to filter out interference noise. Built-in temperature sensor and electromechanical self-test function are reserved for routine equipment performance inspection.

Supply voltage range is 2.25V~3.6V; operating current is 200μA under normal measurement mode, standby current only 21μA, perfectly suited for battery-powered wireless sensor terminals. Maximum internal signal bandwidth can reach 1.5kHz, capable of capturing high-frequency vibration shock signals.

Adopts 14-pin hermetic LCC surface mount packaging, overall dimension 6mm×5.6mm×2.2mm. The metal sealed cavity structure effectively prevents moisture and dust erosion, ensuring consistent sensor performance under harsh environmental conditions. It belongs to MSL3 moisture sensitive component, reflow soldering procedures must be completed within 168 hours after opening original vacuum packaging. Standard reel packaging with 500 pieces per reel is provided to match fully automatic placement equipment feeding requirements.

Wide temperature working range covers -40℃ ~ +125℃, adapting to outdoor monitoring equipment, industrial cabinet and vehicle-mounted electronic devices with severe temperature fluctuation. The whole product is produced with lead-free process and complies with global environmental material restriction standards. Compact packaging occupies minimal PCB layout space, and the integrated circuit structure simplifies peripheral signal conditioning circuit design.
