ADXL345
The digital accelerometer measures three axes with selectable ±2 g, ±4 g, ±8 g, and ±16 g ranges. It provides up to 13-bit resolution with digital output over I2C or 3-wire/4-wire SPI interfaces. The device operates from a 2.0 V to 3.6 V supply and supports I/O supply operation down to 1.7 V. Integrated motion functions include tap detection, activity and inactivity detection, free-fall detection, and a 32-level FIFO. The sensor is supplied in a compact 14-terminal LGA package rated for -40 °C to +85 °C operation.
