Mingjiada Electronics Supplies and Recycles ADI ADXL357 Low-Noise Three-Axis MEMS Accelerometers — For UAVs and Industrial Inertial Sensing

In UAV flight control, platform stabilisation and condition monitoring designs, accelerometers directly influence attitude estimation, vibration suppression and long-term drift performance. Shenzhen Mingjiada Electronics Co., Ltd. — provides genuine, in-stock supply and surplus stock recycling services for the ADI ADXL357 low-noise triaxial MEMS accelerometer, catering to customers in the drone, robotics, structural health monitoring and industrial condition monitoring sectors, and supporting samples, small-batch trial production and bulk order fulfilment.

I. ADXL357 Product Overview

The ADXL357 is a digital-output, three-axis MEMS accelerometer launched by ADI, positioned as ‘low-noise, low-drift and low-power’, primarily targeting high-performance industrial and inertial measurement applications. The ADXL357 supports ranges of ±10 g and ±20 g, offering low noise, minimal offset drift and long-term stability across the temperature range, enabling precision applications with minimal calibration requirements.

II. The main specifications of the ADXL357 are as follows:

Measurement axes: X/Y/Z (three axes); configurable ranges of ±10 g, ±20 g and ±40 g

Output interface: Digital SPI, limited I²C; built-in 20-bit ADC

Noise spectral density: Typically 75 μg/√Hz (all axes, as stated on the official Chinese page; some documentation lists 80 μg/√Hz depending on range/test conditions)

0g offset temperature drift: up to 0.75 mg/°C (−40 to +125 °C)

Power consumption: typical 200 μA in measurement mode (VSUPPLY, LDO enabled); 21 μA in standby

Power supply: VSUPPLY 2.25–3.6 V (internally regulated); typically 1.8 V ± 10% for V1P8 (analogue/digital) when bypassing the LDO

Filtering: Programmable high-pass/low-pass digital filtering, supporting synchronous sampling data interpolation

Temperature sensing: Integrated temperature sensor

Package/Environment: 14-pin LCC, 6 × 5.6 × 2.2 mm; operating temperature −40 to +125 °C; hermetically sealed package for long-term stability

IV. Why it is Suitable for Drones and Unmanned Systems

The official applications for the ADXL357 cover IMUs, AHRS, platform stabilisation, tilt detection, robotics, condition monitoring, structural health monitoring and seismic imaging. In the context of drones, its value lies primarily in three areas:

1. Tilt measurement under high vibration: Resonance from drone motors, propellers and the airframe generates continuous vibration. The ADXL357’s low noise and low 0g drift characteristics enable precise tilt measurements in high-vibration environments, reducing attitude errors caused by vibration.

2. More stable IMU/AHRS front-end: As a three-axis accelerometer input, it works in conjunction with gyroscopes to form an IMU/AHRS, used for flight attitude reference, platform stabilisation and landing attitude determination; The 20-bit ADC and programmable filtering facilitate noise reduction in subsequent fusion algorithms.

3. Wide temperature range and low power consumption for airborne nodes: −40 to +125 °C, 200 μA measurement current, and dual SPI/I²C interfaces facilitate board layout for flight control motherboards, wireless sensor nodes and redundant attitude modules.

In applications such as drone flight control, industrial IMUs, robotic attitude control, platform stabilisation and vibration monitoring, the noise, zero-offset drift and long-term stability of accelerometers directly affect system accuracy.
