Dual-Axis ±1.7 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 ±1.7g (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 capacitors CX and CY 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.
