CN0350 for Piezo strain

Hi Lin,

The ADA4051-2 has very low offset voltage and would probably be a better choice than the AD8502.

Since the bandwidth of your signal is only 20Hz, the gain-bandwidth of the ADA4051-2 is high enough.

Best Regards,

Walt

What about LTC2067. Will it be better than ADA4051-2

Hi Plawat,

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.?
