The ADIS16006 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 ADIS16006 measures acceleration with a full-
scale range of ±5 g (minimum). The ADIS16006 can measure both
dynamic acceleration (vibration) and static acceleration (gravity).
The typical noise floor is 200 µg/√Hz, allowing signals below
1.9 mg (60 Hz bandwidth) to be resolved.
The bandwidth of the accelerometer is set with optional
capacitors, CX and CY, at the XFILT pin and the YFILT pin.
Digital output data for both axes is available via the serial interface.
APPLICATIONS
Industrial vibration/motion sensing
Platform stabilization
Dual-axis tilt sensing
Tracking, recording, analysis devices
Alarms and security devices
An externally driven self-test pin (ST) allows the user to verify
the accelerometer functionality.
The ADIS16006 is available in a 7.2 mm × 7.2 mm × 3.7 mm,
12-terminal LGA package.
