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).

... Displacement of the sensor frame changes the differential capacitance. On-chip circuitry measures the capacitive change. MECHANICAL SENSOR The ADXL001 is built using the Analog Devices SOI MEMS sensor process. The sensor device is micromachined in-plane in the SOI device layer. Trench isolation is used to electrically isolate, but mechanically couple, the differential sensing elements ...

... The fixed fingers in the forcing cells are normally kept at the same potential as that of the movable frame. When the digital self-test input is activated, the ADXL001 changes the voltage on the fixed fingers in these forcing cells on one side of the moving plate. This potential creates an attractive electrostatic force, causing the sensor to move toward those fixed fingers. The entire signal channel is active ...

... The ADXL001 addresses this issue in two ways. First, the high clock frequency, 125 kHz for the output stage, eases the task of choosing a power supply clock frequency such that the difference between it and the accelerometer clock remains well outside the filter bandwidth ...
