Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADXL313WACPZ is a small, thin, low-power 3-axis accelerometer with high resolution (13-bit) and a measurement range of up to ±4 g. The digital output data is in 16-bit binary-complement format and can be accessed through the Serial Port Interface (SPI) (3-wire or 4-wire) or I2C digital interface.

The ADXL313WACPZ is well suited for car alarm or black box applications. It can measure static gravitational acceleration in tilt detection applications, as well as dynamic acceleration due to motion or shock. The device features high-resolution (1024 LSB/g) and low-noise (150 μg/√Hz) performance, and is capable of resolving tilt angle changes as small as 0.1°. The built-in FIFO facilitates the use of oversampling techniques to increase the inclination resolution to 0.025°.

The device offers a variety of built-in detection functions. Motion and non-motion detection functions detect if motion is occurring and if the acceleration on any axis exceeds a user-set limit. These functions can be mapped to interrupt output pins. An integrated 32-level FIFO can be used to store data, reducing host processor intervention to a greater extent and lowering system power consumption.

The low-power mode supports intelligent motion-based power management for threshold sensing and motion acceleration measurements with very low power consumption.

The ADXL313WACPZ is available in a small, ultra-thin, 5 mm × 5 mm × 1.45 mm, 32-pin LFCSP package that is pin-compatible with the ADXL312 accelerometer.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
