Product Description
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessi
ble through either a SPI (3- or 4-wire) or I2C digital interface.
The ADXL345 is well suited for mobile device applications. It meas ures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°
Features
- Working Voltage: 2.0V~3.6V
- I/O Voltage: 1.7V~Vs
- Measurement range: ±2g, ±4g, ±8g, or ±16g
- Communication method: SPI (3- and 4-wire) and I2C digital interfaces
- High resolution (13 bits) and measurement range of ± 16g. Its high resolution (3.9 mg / LSB) enables measurement of tilt angle changes of less than 1.0 °
- ULTRA LOW POWER: as low as 23 μA in measurement mode and 0.1 μA in standby mode at VS = 2.5 V (typical)
- Wide temperature range (−40°C to +85°C)
Typical applications
- Handsets
- Medical instrumentation
