GENERAL DESCRIPTION

The ADXL001 is a major advance over previous generations of

accelerometers providing high performance and wide bandwidth.

This part is ideal for industrial, medical, and military applications

where wide bandwidth, small size, low power, and robust

performance are essential.

Using the Analog Devices, Inc. proprietary fifth-generation

iMEMs® process enables the ADXL001 to provide the desired

dynamic range that extends from ±70 g to ±500 g in combin-

ation with 22 kHz of bandwidth. The accelerometer output

channel passes through a wide bandwidth differential-to-single-

ended converter, which allows access to the full mechanical

performance of the sensor.

The part can operate on voltage supplies from 3.3 V to 5 V.

The ADXL001 also has a self-test (ST) pin that can be asserted to

verify the full electromechanical signal chain for the accelerometer

channel.

The ADXL001 is available in the industry-standard 8-terminal

LCC and is rated to work over the extended industrial temperature

range (−40°C to +125°C).
