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
The ADXL278 is the fourth-generation surface micromachined
iMEMS® accelerometer from ADI 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.
