ADXL345TCCZ-EP-RL

Accelerometer Triple 2g/ 4g/ 8g/ 16g 2.5V 14Pin LGA T/R

Product Details

The ADXL345 is a small, thin, low 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 accessible through either a SPI 3- or 4-wire or I2C digital interface.

The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution 4 m_g_/LSB enables measurement of inclination changes less than 1.0°.

Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out FIFO buffer can be used to store data to minimize host processor intervention.

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

The ADXL345 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead, plastic package.
