ADXL355BEZ-RL7 Обзор
An accelerometer is a MEMS (micro-electromechanical systems) sensor that measures proper acceleration along one or more axes and converts it to an electrical signal. The ADXL355 belongs to the broader category of motion sensors, which sits under inertial measurement units (IMUs) and ultimately under semiconductor transducers. Digital-output MEMS accelerometers use an internal sigma-delta ADC so that the host MCU reads clean 20-bit counts over SPI or I²C instead of amplifying a small analog signal.
Key features include 25 µg/NL noise density (X/Y axes) — about 2-3× lower than typical consumer accelerometers — ±0.15 mg/°C zero-g offset drift (typ.) for high stability over temperature, ±25 mg typical zero-g offset accuracy after factory trim, and a built-in 32-sample FIFO that lets the host MCU sleep while the sensor buffers data. A dedicated temperature sensor and four user-selectable low-pass filters (ODR/2, ODR/4, ODR/8, ODR/16, with ODR up to 4 kHz for digital decimation) are also integrated.
The ADXL355BEZ-RL7 architecture pairs a polysilicon surface-micromachined proof mass with a differential capacitance readout front end and a 20-bit sigma-delta ADC. The ceramic LCC (leadless chip carrier) package provides excellent thermal stability and a robust land pattern for industrial and medical assemblies.
Typical applications include industrial IoT vibration sensing, inertial measurement units for unmanned aerial vehicles (UAVs), structural health monitoring, tilt/inclination measurement, and seismic imaging. The low noise and low drift make it especially suited for long-term condition-monitoring installations where sensor recalibration is impractical.
When designing with this device, note that the ADXL355BEZ-RL7 does not include the highest ±312 g range offered by the wider family (ADXL356/357), nor the analog-output variants (ADXL354/ADXL354C). Use ADXL356/357 if a wider range or analog output is needed; use ADXL354 if a continuous analog signal is preferred. The -RL7 suffix indicates 7-inch reel packaging (1,000-piece reel).
This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers select and source the right ADXL355 variant for high-precision inertial applications.

Типичное применение
ADXL355BEZ-RL7 подходит для 6 применениеs: Industrial Vibration & Condition Monitoring, Inertial Measurement Units for UAVs & Drones, Structural Health Monitoring (Bridges, Buildings, Towers), Precision Tilt & Inclination Sensing, Seismic Imaging & Geophysics, Medical Patient Monitoring & Wearables.
Industrial Vibration & Condition Monitoring
The ADXL355BEZ-RL7's 25 µg/NL noise density (X/Y) and ±0.15 mg/°C zero-g offset drift make it ideal for long-term condition monitoring on pumps, motors, and rotating machinery where recalibration is impractical. The integrated 32-sample FIFO buffers samples while the host MCU sleeps, reducing wireless sensor node power. Placed on a 4-layer PCB with a guard ring around the LCC land pattern and a 0.1 µF decoupling capacitor within 3 mm of VSUPPLY, the sensor reliably detects sub-100 Hz vibration signatures indicating bearing wear before catastrophic failure. Compared to consumer-grade accelerometers, its 2-3× lower noise extends detection lead time by months in predictive-maintenance deployments.

Inertial Measurement Units for UAVs & Drones
In UAV flight controllers, the ADXL355BEZ-RL7 serves as a high-stability tilt reference supplementing gyroscopes, providing accurate pitch/roll during low-acceleration maneuvers and GPS-denied hovering. The ±2 g range delivers maximum resolution for attitude estimation, while the 1.5 kHz ODR supports vibration rejection from motors. The ceramic LCC package offers robust thermal stability across -40 °C to +85 °C drone operating temperatures. Unlike consumer-grade IMUs, the ADXL355BEZ-RL7's ±0.15 mg/°C drift ensures consistent flight behavior across cold-warm cycles, critical for autonomous drone operations.

Structural Health Monitoring (Bridges, Buildings, Towers)
The ADXL355BEZ-RL7's low 25 µg/NL noise density and ±0.15 mg/°C offset drift suit long-term SHM installations where sensor calibration is rarely possible. Mounted at multiple points on a bridge or tower, the sensor captures modal frequencies down to 0.1 Hz and detects micro-vibrations from traffic or wind loading. The SPI interface streams 20-bit data to a wireless gateway, while the integrated temperature sensor compensates for thermal expansion effects on the structure. Compared to piezoelectric accelerometers, the ADXL355BEZ-RL7 is far more compact and operates from a single 3.3 V rail — eliminating charge amplifiers and high-voltage bias supplies.

Precision Tilt & Inclination Sensing
For static inclination measurement in surveying equipment, solar trackers, and platform leveling, the ADXL355BEZ-RL7's ±0.15 mg/°C zero-g drift and low noise floor enable sub-0.01° tilt resolution after temperature compensation. The ±2 g setting maximizes sensitivity for gravity-vector alignment. The selectable ODR/16 low-pass filter rejects mechanical vibration noise from nearby machinery, and the FIFO reduces host MCU wakeup overhead — enabling battery-powered inclinometers that last years on a single cell. Unlike MEMS inclinometers with integrated algorithms, the ADXL355BEZ-RL7 gives engineers freedom to apply custom calibration and filtering.

Seismic Imaging & Geophysics
In seismic sensor nodes and geophysical exploration, the ADXL355BEZ-RL7's 25 µg/NL noise floor detects ground motion below 1 Hz for oil/gas exploration and earthquake early-warning networks. The 1.5 kHz ODR with selectable low-pass filters captures both teleseismic (0.01-1 Hz) and local-event (1-100 Hz) spectra. The ceramic LCC package survives harsh field deployment environments, and the 32-sample FIFO synchronizes with sparse wireless transmissions in remote sensor arrays. Compared to analog-output geophones, the ADXL355BEZ-RL7 directly digitizes at the sensor — eliminating analog cable noise and ground loops across long sensor arrays.
Рекомендуется
Medical Patient Monitoring & Wearables
The ADXL355BEZ-RL7's low power operation and high sensitivity suit wearable patient monitors measuring posture, gait, fall detection, and respiratory rate. With ±0.15 mg/°C drift, the sensor delivers consistent readings across body-temperature variations, and the SPI/I²C interface integrates with low-power BLE SoCs. The MSL 1 unlimited floor life simplifies medical device manufacturing logistics. Compared to consumer wearables with proprietary algorithms, the raw 20-bit digital output gives medical OEMs full control over signal processing — enabling FDA-grade validation of motion-based diagnostics.

Заметки по проектированию
Place a 0.1 µF X7R ceramic decoupling capacitor within 3 mm of the VSUPPLY pin, plus a 1 µF bulk capacitor on the same rail. The V1P8ANA and V1P8DIG internal LDO pins each require their own 0.1 µF + 1 µF decoupling pair as shown in the EVAL-ADXL354/355 reference schematic. A continuous ground pour around the 14-terminal LCC land pattern minimizes thermal gradients that cause offset errors.
Per the Analog Devices EVAL-ADXL354-355 user guide (UG-1030), place a guard ring (grounded trace) around the sensor land pattern to isolate it from board stress. Mechanical stress on the ceramic LCC package is the leading cause of zero-g offset shifts in production; isolate the sensor from screw mounts, stiffeners, and high-CTE areas of the PCB. Maintain symmetric land pattern dimensions on all four sides for consistent solder fillet formation.
Estimated: at 1.5 kHz ODR with SPI clocked at 5 MHz, continuous sample streaming consumes approximately 2 mA on the 3.3 V supply — use the FIFO (32-sample) and burst-read to put the host MCU to sleep between bursts. The integrated temperature sensor is for compensation only and is not factory-calibrated for absolute °C accuracy; calibrate against an external temperature reference if absolute measurements are required.
