ADIS16003:  Dual-Axis ±1.7 g Accelerometer with SPI Interface

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).

The typical noise floor is 110 µg/√Hz, allowing signals below 1 mg (60 Hz bandwidth) to be resolved.

The bandwidth of the accelerometer is set with optional capaci-tors C_X and C_Y at the XFILT and YFILT pins. Selection of the two analog input channels is controlled via the serial interface.

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

The ADIS16003 is available in a 7.2 mm × 7.2 mm × 3.7 mm, 12-terminal LGA package.
