ADXL193
GENERAL DESCRIPTION
The ADXL193 is a low power, complete single-axis
accelerometer with signal conditioned voltage outputs that are
all on a single monolithic IC. This product measures
acceleration with a full-scale range of ±120 g or ±250 g
(minimum). It can also measure both dynamic acceleration
(vibration) and static acceleration (gravity).
The ADXL193 is a 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 ADXL193 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 ADXL193 is available in a 5 mm × 5 mm × 2 mm,
8-terminal ceramic LCC package.
