... THEORY OF OPERATION The ADXL278 provides a fully differential sensor structure and circuit path, resulting in the industry’s highest resistance to EMI/RFI effects. This latest generation uses electrical feedback with zero-force feedback for improved accuracy and stability. The sensor resonant frequency is significantly higher than the ...

... However, both the power supply clock and the accelerometer clock may vary with time or temperature, which can cause the interference signal to appear in the output filter bandwidth. The ADXL278 addresses this issue in two ways. First, the high clock frequency eases the task of choosing a power supply clock . DC frequency such that the difference between it and the accelero- meter clock remains well outside of the filter bandwidth ...
