APPLICATIONS
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).

The ADXL001 is a major advance over previous generations of
–9
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.
