3-Axis, 0.5 g/ 1 g/ 2 g/ 4 g

Digital Accelerometer

Data Sheet

ADXL313

FEATURES

GENERAL DESCRIPTION

Ultralow power (scales automatically with data rate)

As low as 30 µA in measurement mode (V_S= 3.3 V)

As low as 0.1 µA in standby mode (V_S= 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

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 tilt-sensing applica-

tions, as well as dynamic acceleration resulting from motion or

shock. Its high resolution (1024 LSB/g) and low noise (150 μg/√Hz)

enable resolution of inclination changes of as little as 0.1°. A built-

in FIFO facilitates using oversampling techniques to improve

resolution to as little as 0.025° of inclination.

Several built-in sensing functions are provided. Activity and

inactivity sensing detects the presence or absence of motion and

whether the acceleration on any axis exceeds a user-set level.

These functions can be mapped to interrupt output pins. An

integrated 32-level FIFO can be used to store data to minimize

host processor intervention, resulting in reduced system power

consumption.

Low power modes enable intelligent motion-based power

management with threshold sensing and active acceleration

measurement at extremely low power dissipation.

Pb free/RoHS compliant

Small and thin: 5 mm × 5 mm × 1.45 mm LFCSP package

Qualified for automotive applications

The ADXL313 is supplied in a small, thin 5 mm × 5 mm ×

1.45 mm, 32-lead LFCSP package and is pin compatible with

the ADXL312 accelerometer device.

APPLICATIONS

Car alarms

Hill start aid (HSA) systems

Electronic parking brakes

Data recorders (black boxes)
