Functional Block Diagram APPLICATIONS Vibration Monitoring Shock Detection Sports Diagnostic Equipment Medical Instrumentation Industrial Monitoring 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). 40.0 35.0 30.0 25.0 Response (dB) 20.0 15.0 10.0 5.0 0.0 -5.0 -10.0 1 10 100 1000 10000 100000 Frequency (Hz) Figure 2.
