ADXL278:  Small, Low Power, Dual Axis High-g iMEMS® Accelerometer With Analog Output

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 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.
