GENERAL DESCRIPTION
The ADXL190 is a complete acceleration measurement system
on a single monolithic IC. It contains a polysilicon surface-
micromachined sensor and signal conditioning circuitry to
implement an open-loop acceleration measurement architecture.
The ADXL190 is capable of measuring both positive and nega-
tive accelerations up to 100 g, making it suitable for shock and
vibration measurement.
Typical noise floor is 4 mg/ Hz allowing signals below 40 milli-g
to be resolved. The ADXL190 can measure both dynamic accel-
erations, (typical of vibration) or static accelerations, (such as
inertial force or gravity).
The ADXL190 has a two-pole Bessel switched-capacitor filter.
Bessel filters, sometimes called linear phase filters, have a step
response with minimal overshoot and a maximally flat group

delay. The –3 dB frequency of the poles is preset at the factory
to 400 Hz. These filters are also completely self-contained and
buffered, requiring no external components.
The product features a built-in self-test feature that exercises
both the mechanical structure and electrical circuitry. When
triggered by a logic high on the self-test pin, an electrostatic
force acts on the beam equivalent to approximately 20% of full-
scale acceleration input, and thus a proportional voltage change
appears on the output pin. No external components other than a
decoupling capacitor are required.
The ADXL190 is available in a hermetic 14-lead surface mount
cerpak, specified over the –40 C to +105 C temperature range.
