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.
Utilizing our proprietary 5th Generation iMEMs process
enables the ADXL001 to provide the desired dynamic range that
extends from +/-70g to +/-500g in combination with 22kHz 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 3.3V to 5V.
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 industry standard 8 pin LCC and
is rated to work over the extended industrial temperature range
(-40 to +125C).
