Product Introduction
1 ADXL345 is a small and thin ultra-low power 3-axis accelerometer with high resolution (13 bits) and a measuring range of ± 16g? The digital output data is in 16 bit binary complement format, which can be accessed through SPI (3-wire or 4-wire) or IC digital interface;
2. ADXL345 is suitable for mobile device applications. It can measure static gravity acceleration in tilt detection applications, as well as dynamic acceleration caused by internal motion or impact. It has high resolution (4mg/LSB) and can measure tilt angle changes of 0.25 °. When using ADXL345 digital output acceleration, there is no need for digital to analog conversion, thus saving system costs and circuit board area.
