GENERAL DESCRIPTION
The ADXL78 is a low power, complete single-axis accelerometer
with signal conditioned voltage outputs that are on a single
monolithic IC. This product measures acceleration with a full-
scale range of ±35
g
, ±50
g
, or ±70
g
(minimum). It can also
measure both dynamic acceleration (vibration) and static
acceleration (gravity).
The ADXL78 is the fourth-generation surface micromachined
i
MEMS 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 ADXL78 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 ADXL78 is available in a 5 mm × 5 mm × 2 mm,
8-terminal ceramic LCC package.
