ADXL313

Data Sheet 3-Axis, ±0.5 g/±1 g/±2 g/±4 g Digital Accelerometer ADXL313 FEATURES GENERAL DESCRIPTION Ultralow power (scales automatically with data rate) As low as 30 μA in measurement mode (VS = 3.3 V) As low as 0.1 μA in standby mode (VS = 3.3 V) Low noise performance 150 μg/√Hz typical for X- and Y-axes 250 μg/√Hz typical for the Z-axis Embedded, patent pending FIFO technology minimizes host processor load User-selectable resolution Fixed 10-bit resolution for any g range Fixed 1024 LSB/g sensitivity for any g range Resolution scales from 10-bit at ±0.5 g to 13-bit at ±4 g Built-in motion detection functions for activity/inactivity monitoring Supply and I/O voltage range: 2.0 V to 3.6 V SPI (3-wire and 4-wire) and I2C digital interfaces Flexible interrupt modes mappable to two interrupt pins Measurement range selectable via serial command Bandwidth selectable via serial command Wide temperature range (−40°C to +105°C) 10,000 g shock survival Pb free/RoHS compliant Small and thin: 5 mm × 5 mm × 1.45 mm LFCSP package Qualified for automotive applications The ADXL313 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ±4 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3-wire or 4-wire) or I2C digital interface. The ADXL313 is well suited for car alarm or black box applications. It measures the static acceleration of gravity in tiltsensing application...
