Dear sir,
I am working on Structural Health monitoring project in which i need to sense the voltage generated by piezo.
This piezo has capacitance near about 5nF and it generates voltage waveforms of frequency around 500kHz in the range -5mV to 5mV. I need a opamp which should be able to sense this voltage and amplify it in the voltage range 0-3V.
I have tried this with THS3091 opamp but it won't be able to sense the voltages. Kindly help me to find a correct opamp with larger input impedance.
Thank you
