GENERAL DESCRIPTION

FEATURES

Dual-axis accelerometer

The ADIS16003 is a low cost, low power, complete dual-axis

accelerometer with an integrated serial peripheral interface

(SPI). An integrated temperature sensor is also available on the

SPI interface. The ADIS16003 measures acceleration with a full-

scale range of ±1.7 g (minimum), and it can measure both

dynamic acceleration (vibration) and static acceleration

(gravity).

SPI® digital output interface

Internal temperature sensor

Highly integrated; minimal external components;

bandwidth externally selectable

1 mg resolution at 60 Hz

Externally controlled electrostatic self-test

3.0 V to 5.25 V single-supply operation

The typical noise floor is 110 μg/√Hz, allowing signals below

1 mg (60 Hz bandwidth) to be resolved.

Low power: <2 mA

3500 g shock survival

7.2 mm × 7.2 mm × 3.6 mm package

The bandwidth of the accelerometer is set with optional capaci-

two analog input channels is controlled via the serial interface.

APPLICATIONS

Industrial vibration/motion sensing

An externally driven self-test pin (ST) allows the user to verify

the accelerometer functionality.

Platform stabilization

Dual-axis tilt sensing

Tracking, recording, analysis devices

The ADIS16003 is available in a 7.2 mm × 7.2 mm × 3.6 mm,

12-terminal LGA package.
