Mingjiada Supply/Recycle ADI ADXL312 Low Power 3-Axis Digital Accelerometer

Mingjiada Electronics supplies and recycles the ADI ADXL312 low-power triaxial digital accelerometer (LFCSP-32) – a commonly used MEMS chip for drone and industrial attitude sensing
In drone flight control, gimbal stabilisation, vehicle black box systems and industrial vibration monitoring designs, the triaxial digital accelerometer is one of the core sensors that determine attitude calculation accuracy and system standby power consumption. The ADXL312 (commonly referred to as ADXL312ACPZ) from ADI (Analog Devices), with its ±12g measurement range, 13-bit resolution, typical operating current of 57μA and compact 32-pin LFCSP package, has become a cost-effective MEMS solution for small-to-medium payload drones and portable devices. Shenzhen Mingjiada Electronics Co., Ltd. – currently offers brand-new, genuine ADXL312 units in stock, whilst simultaneously operating a high-value buy-back service for surplus drone components, factory-surplus ADXL312 units and the full range of ADI sensors.

ADXL312 is a compact, slim, low-power triaxial accelerometer capable of high-resolution (13-bit) measurements of acceleration up to ±12 g. The 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.

ADXL312 is suitable for automotive alarm or ‘black box’ applications. It can measure static gravitational acceleration in tilt detection applications, as well as dynamic acceleration caused by motion or impact. The device features high resolution (2.9 mg/LSB), capable of resolving tilt changes as small as 0.25°. The built-in FIFO facilitates the use of oversampling techniques to enhance tilt resolution to 0.05°.
