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).
