Hi, I have read your CN0350 , it seems design for a piezoelectric accelerometer.
Can I use it to measure the piezoelectric strain ? How to modify it??
Thank you so much.
Note that this thread is 6 years old, you should start a new question in the amplifiers forum.
Or, given that the CN0350 is a complete digitizer, there may be a more modern ADC that does not require any external signal conditioning. The AD7124-4 is the first part that comes to mind - it's got a sample rate as high as 19.2 ksps, and a built-in PGA.
But again - better to ask in those product forums with your specific requirements - include a datasheet for the piezo strain gauge you are using, and, which specs are most important in your end application (power consumption? Sample rate? Accuracy - offset, gain error, drift, etc.?
