会社ブログについて Mingjiada Electronics Supply and Procurement of ADXL355: Professional Channel for 3-axis Digital Output Accelerometers Specifically Designed for Drones

The ‘Perception Cornerstone’ of UAV Flight Control: Why the ADXL355 Is the Preferred Choice for Industrial Applications

Amid the rapid development of the low-altitude economy and the intelligent unmanned systems industry, accelerometers—as the core sensing components of flight control systems and inertial navigation—directly determine the accuracy of an unmanned aerial vehicle’s attitude estimation and its flight safety rating. The ADXL355, launched by Analog Devices (ADI), is a low-noise, low-drift, low-power, digital-output, 3-axis MEMS accelerometer specifically designed for high-end inertial measurement applications. With its industry-leading noise performance and temperature stability, the ADXL355 has become the sensor of choice for flight control designs in industrial-grade drones, surveying drones and long-endurance inspection platforms.

Key Technical Advantages: Ultra-low noise, extremely low temperature drift and integrated digital output

The ADXL355’s core competitiveness is reflected in three key areas.

Ultra-low noise density. The ADXL355’s typical noise density across all axes is just 22.5 µg/√Hz, enabling it to accurately capture faint low-frequency vibration signals and provide UAVs with raw acceleration data featuring a high signal-to-noise ratio. This means that flight control algorithms can operate at lower filter cut-off frequencies, thereby obtaining a more accurate dynamic response during attitude calculation.

Extremely low 0g offset temperature drift. The maximum variation in the full-axis 0g offset relative to temperature is only 0.15 mg/°C, far superior to that of traditional MEMS accelerometers. For drones operating outdoors and subjected to extreme temperature fluctuations, this characteristic significantly reduces the gradual drift in attitude angles caused by temperature drift, thereby alleviating the engineering burden of frequent calibration within the flight control system.

Digital output and flexible interfaces. The ADXL355 incorporates a 20-bit Σ-Δ analogue-to-digital converter, which outputs digital acceleration data directly, thereby avoiding noise coupling issues associated with analogue signal transmission. The device supports both SPI and I²C digital interfaces, with selectable measurement ranges of ±2g, ±4g and ±8g, and is equipped with programmable high-pass and low-pass digital filters, with bandwidth flexibly configurable within the range of 1 Hz to 1,000 Hz. With a measurement mode current of just 200 µA and a standby current as low as 21 µA, it offers significant energy-saving advantages for drone platforms reliant on battery life.

Four Key Applications in the Drone Sector

1. Attitude Estimation and Stabilisation Control. The ADXL355 continuously monitors the aircraft’s tilt angle and changes in body acceleration. Working in conjunction with a gyroscope to perform IMU inertial measurement, it provides the flight controller with high-frequency, low-latency attitude reference data, significantly enhancing gimbal stabilisation and the airframe’s resistance to vibrations.

2. Core component of the AHRS (Attitude and Heading Reference System). In flight conditions where GPS signals are lost or disrupted, the high-precision gravity tilt data output by the ADXL355 serves as the core input for the AHRS, helping the drone maintain a stable attitude estimate even without satellite positioning.

3. Vibration monitoring and fault early warning. By collecting vibration data from the motors and airframe, the ADXL355 can monitor abnormal vibration characteristics of the airframe in real time, providing early fault feedback signals to the flight control system and reducing the risk of crashes caused by mechanical failures.

4. Tilt Measurement in High-Altitude Environments. The sealed LCC package and wide operating temperature range (-40°C to +125°C) enable the ADXL355 to maintain excellent repeatability in tilt measurements during flight scenarios involving alternating high and low temperatures, thereby reducing the disruption to flight missions caused by frequent calibration.

Mingjiada Electronics: Reliable Supply and Recycling Channels for the ADXL355

Established in 1996, Shenzhen Mingjiada Electronics Co., Ltd. is a globally authorised independent distributor of electronic components certified to the ISO 9001 quality management system. With branches in Hong Kong, Japan, Russia and Taiwan, the company maintains a stock of over 2 million line items and has long provided customers with a full range of ADI sensor products.

Stock availability service. Mingjiada maintains a safety stock of the ADXL355 at its temperature- and humidity-controlled warehousing centres in Shenzhen and Hong Kong, with a focus on supplying models such as the ADXL355BEZ (LCC-14 hermetically sealed package). We support both small-batch sample testing and large-volume order fulfilment, with standard models available for same-day dispatch. All components are sourced through official channels from the original manufacturer or first-tier distributors, accompanied by original manufacturer labels, batch numbers and traceable Certificates of Conformity (COC). We guarantee that all products are brand-new and original, with no refurbished or loose new items.

High-value purchase and recycling services. Mingjiada serves global manufacturers, distributors and R&D teams, offering long-term cash purchases of ADXL355 surplus stock, obsolete stock, end-of-line stock and dismantled components. We accept both small and large batches, providing 24-hour rapid valuation and cash settlement services, with a particular focus on recycling components from drone flight controllers and industrial sensors. Customers can utilise this service to clear inventory, free up capital and achieve the efficient circulation of supply chain resources.

Complementary component support. In addition to the ADXL355, Mingjiada also supplies and recycles a full range of drone electronic components, including gyroscopes, IMU modules and flight control chips, providing a one-stop component supply and procurement service for drone manufacturers and solution providers.
