company blog about Large Supply of ADI ADXL343 Three-Axis MEMS Accelerometers to Empower Consumer Electronics and Industrial Sensing Applications

As a specialist supplier of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. has long supplied large quantities of genuine ADXL343 (ADXL343BCCZ) three-axis MEMS accelerometers, offering ample stock and rapid delivery.

Product Overview: The ADXL343 is a high-performance, low-power digital MEMS accelerometer

The ADXL343 is a versatile, low-power, 3-axis digital output MEMS accelerometer launched by Analog Devices Inc. (ADI). It utilises a compact 3 mm × 5 mm × 1 mm LGA package and integrates high-resolution sensing with comprehensive motion detection capabilities within a single device, enabling the simultaneous measurement of static gravitational acceleration (for tilt detection) and dynamic acceleration caused by motion or impact.

The device supports selectable measurement ranges (±2g, ±4g, ±8g, ±16g) and a 13-bit high-resolution output, with a sensitivity of up to 3.9 mg/LSB, sufficient to resolve tilt angle changes of less than 1.0°. Its digital output is accessible via SPI (3-wire/4-wire) or I²C interfaces, facilitating connection to various microcontrollers (MCUs), and supports a power consumption mode as low as 23 µA along with a built-in 32-level FIFO buffer, effectively reducing the system’s overall power consumption.

ADXL343 Key Technical Specifications

Measurement range: ±2g, ±4g, ±8g, ±16g (selectable)

Resolution: 13-bit (3.9 mg/LSB)

Digital interfaces: SPI (3-wire/4-wire) and I²C

Supply voltage: 2.0 V to 3.6 V

Shock resistance: 10,000 g

Operating Temperature: –40°C to +85°C

Package Dimensions: 3 mm × 5 mm × 1 mm LGA

Integrated Functions: Single-tap/double-tap detection, active/inactive detection, free-fall detection

Key Applications: From consumer electronics to industrial monitoring

Thanks to its high precision, low power consumption and rugged design, the ADXL343 is suitable for a wide range of applications:

1. Smartphones and handheld devices

In handheld devices such as mobile phones and tablets, the ADXL343 enables automatic screen rotation, pedometer functions, motion-based game controls and tap/double-tap interactions, significantly enhancing the user experience.

2. Gaming and pointing devices

In games controllers, virtual reality (VR) controllers and wireless mice, this sensor accurately captures hand posture and movement trajectories, providing smooth and precise pointing and motion control.

3. Industrial Equipment and Hard Disk Drive Protection

With a shock resistance of up to 10,000 g, the ADXL343 is ideally suited for vibration monitoring in industrial instruments and drop protection for hard disk drives (HDDs). When the device is detected to be in free fall, the sensor can promptly trigger a head repositioning operation to prevent data corruption.

4. Wearable Devices and the Internet of Things (IoT)

In smartwatches, fitness trackers and portable medical monitoring devices, this device offers significant advantages in terms of ultra-low power consumption and compact size, making it suitable for activity tracking, sleep analysis and fall detection. Furthermore, its integrated activity/inactivity detection function makes it an ideal choice for motion-activated wake-up in IoT nodes.

5. Structural Health Monitoring and Tilt Sensing

The ADXL343 has been utilised in structural health monitoring (such as smart motor sensing and horizontal position change detection). It is equally suitable for high-precision inclinometers, platform stabilisation control and security alarm systems.
