Mingjiada Supply/Recycle ADI ADXL350 Low Power 3-Axis Digital Accelerometer For UAV Attitude Sensing

Mingjiada Electronics Supplies/Recycles ADI ADXL350 Low-Power Tri-Axis Digital Accelerometer | Drone Attitude and Low-Power Sensing Applications

With the accelerating adoption of drone technology in sectors such as industrial inspection, agricultural crop protection, logistics and delivery, and security surveillance, flight stability, attitude sensing accuracy and environmental adaptability are becoming key metrics for drone manufacturers to compete on. Shenzhen Mingjiada Electronics Co., Ltd. — catering to customers in the drone and inertial sensing sectors — has long provided genuine ADI ADXL350 triaxial digital accelerometers whilst simultaneously offering high-value buy-back services for devices in the same series and other ADI MEMS components, thereby helping both R&D departments and manufacturing facilities resolve the dual challenges of ‘procuring scarce components’ and ‘monetising idle stock’.

I. ADXL350: A Low-Power 3-Axis Accelerometer Designed for High-Performance Attitude Sensing

The ADXL350 is a compact, low-profile, low-power 3-axis accelerometer launched by ADI, featuring high resolution (13-bit) and a selectable measurement range of up to ±8g. The ADXL350 offers industry-leading temperature performance, ensuring minimum and maximum offset specifications across the temperature range. Digital output data is in 16-bit two’s complement format and can be accessed via SPI (3-wire or 4-wire) or I²C digital interfaces.

The ADXL350 is ideally suited for high-performance portable applications. It can measure static gravitational acceleration in tilt-detection applications, as well as dynamic acceleration caused by motion or impact. With its high resolution (2 mg/LSB), it is capable of resolving tilt changes of less than 1.0°.

The ADXL350’s low-power mode supports motion-based intelligent power management, enabling threshold sensing and motion acceleration measurement with extremely low power consumption.

II. ADXL350 Core Specifications:

Measurement range: Selectable ±1g / ±2g / ±4g / ±8g

Resolution: Up to 13 bits (at ±8g), 2 mg/LSB

Output resolution: 16-bit two’s complement

Interface type: SPI (3-wire/4-wire), I²C

Operating voltage: 2.0 V to 3.6 V

Measurement mode current: 45 μA (VS = 2.5 V, typical)

Standby mode current: 0.1 μA (typical)

Operating temperature: –40 °C to +85 °C

Package dimensions: 3 mm × 4 mm × 1.2 mm, 16-pin LGA

III. ADXL350 Product Features:

Excellent zero-g offset accuracy and stability across the full measurement range

Ultra-low power consumption: as low as 45 μA in measurement mode and 0.1 μA in standby mode (typical) at VS = 2.5 V; power consumption varies automatically in proportion to the bandwidth

Power consumption automatically scales proportionally with bandwidth

User-selectable resolution

- 10-bit fixed resolution

- Full resolution, with resolution increasing as the g-range increases, reaching a maximum resolution of 13 bits at ±8 g (maintaining a proportional coefficient of 2 mg/LSB across the entire g-range)

An embedded, 32-level FIFO buffer minimises the load on the host processor

Single-click/double-click detection and free-fall detection

Active/inactive monitoring

Supply voltage range: 2.0 V to 3.6 V

I/O voltage range: 1.7 V to VS

SPI (3-wire and 4-wire) and I²C digital interfaces

IV. Core Applications of the ADXL350 in the Drone Sector

Drone flight control systems require real-time acquisition of the aircraft’s attitude angles (pitch and roll) and motion state. Thanks to its high resolution and low noise, the ADXL350 plays an indispensable role in the following scenarios:

Attitude calculation and stabilisation control for flight control systems.

Vibration monitoring and flight stability optimisation.

Optimisation of battery life through low power consumption.

Other applications:

Portable consumer electronics

High-performance medical and industrial applications
