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.
