Dual-Axis ±1.7 g Accelerometer with SPI Interface Data Sheet ADIS16003 FEATURES GENERAL DESCRIPTION Dual-axis accelerometer
The ADIS16003 is a low cost, low power, complete dual-axis
SPI digital output interface
accelerometer with an integrated serial peripheral interface
Internal temperature sensor
(SPI). An integrated temperature sensor is also available on the
Highly integrated; minimal external components
SPI interface. The ADIS16003 measures acceleration with a full-
Bandwidth externally selectable
scale range of ±1.7 g (minimum), and it can measure both dynamic
1 mg resolution at 60 Hz
acceleration (vibration) and static acceleration (gravity).
Externally controlled electrostatic self-test
The typical noise floor is 110 μg/√Hz, allowing signals below
3.0 V to 5.25 V single-supply operation
1 mg (60 Hz bandwidth) to be resolved.
Low power: <2 mA 3500 g shock survival
The bandwidth of the accelerometer is set with optional capaci-
7.2 mm × 7.2 mm × 3.7 mm package
tors CX and CY at the XFILT and YFILT pins. Selection of the

two analog input channels is controlled via the serial interface.
APPLICATIONS
An externally driven self-test pin (ST) allows the user to verify the accelerometer functionality.
Industrial vibration/motion sensing Platform stabilization
The ADIS16003 is available in a 7.2 mm × 7.2 mm × 3.7 mm,
Dual-axis tilt sensing
12-terminal LGA package.
