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.

THEORY OF OPERATION The ADXL193 provides a fully differential sensor structure and circuit path, resulting in the industry’s highest resistance to EMI/RFI effects. This latest generation uses electrical feedback with zero-force feedback for improved accuracy and stability. The sensor resonant ...

... In any clocked system, power supply noise near the clock frequency may have consequences at other frequencies. An internal clock typically controls the sensor excitation and the signal demodulator for micromachined accelerometers. If the power supply contains high frequency spikes, they may be demodulated and interpreted as an acceleration signal. A signal appears as the difference between the noise frequency and the demodulator frequency ...
