Product Details

The ADXL278 is a low power, complete, dual-axis accelerometer with signal conditioned voltage outputs that are on a single monolithic IC. This product measures acceleration with a full-scale range of X-axis/Y-axis ±35 _g_/±35 _g_, ±50 _g_/ ±50 _g_, or ±70 _g_/±35 _g_ minimum. The ADXL278 can also measure both dynamic acceleration vibration and static acceleration gravity.

The ADXL278 is the fourth-generation surface micromachined _i_MEMS® accelerometer from with enhanced performance and lower cost. Designed for use in front and side impact airbag applications, this product also provides a complete cost-effective solution useful for a wide variety of other applications.

The ADXL278 is temperature stable and accurate over the automotive temperature range, with a self-test feature that fully exercises all the mechanical and electrical elements of the sensor with a digital signal applied to a single pin.

The ADXL278 is available in a 5 mm × 5 mm × 2 mm, 8-terminal ceramic LCC package.
