GENERAL DESCRIPTION

FILTER

SENSOR

The ADXL76, ADXL276, and ADXL269 family of products are

the third generation surface micromachined iMEMS accelero-

meters from Analog Devices with enhanced performance and lower

cost. Designed for use in front and side impact airbag applica-

tions, these products also provide complete cost-effective solutions

useful for a wide variety of other applications.

The ADXL276 is a monolithic two-axis (XY) version of the

ADXL76 with the sensor axes orthogonal (90°) to each other

and in the plane of the chip. It can be used for sensing crashes in

the front or side of the vehicle and can be used to determine the

angle of impact. The ADXL269 is a monolithic two-axis (+X/–X)

version of the ADXL76 with the sensor axes arranged in anti-

parallel orientation (180°) to provide redundancy and elimination

of the need for an external mechanical safing/arming sensor.

The ADXL76, ADXL269, and ADXL276 are 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.
