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.
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.
