MEMS-Based Vibration Analyzer with Frequency Response Compensation

MEMS-Based Vibration Analyzer with Frequency Response Compensation. The circuit offers a high linearity, low noise, wide bandwidth vibration sensing solution. It is ideal for applications requiring a large dynamic range (70 g, 250 g or 500 g) and a flat frequency response from dc to 22 kHz. The proprietary fifth-generation iMEMs process enables the ADXL001 accelerometer to provide dynamic range that extends from 70 g to 500 g in combination with 22 kHz of bandwidth. The AD8606 is a precision, low noise, dual Op-Amp used to create an analog bi-quad filter that flattens the output frequency response of the accelerometer
