Piezoelectric sensor preamplifier

Thank you all,

Thus, it seems that OP07 is somehow left behind by the newest (actually better) types of op. amps.The 400KHz minimum GBW as the DC coupling is most useful info. The chopper stabilized op amps are really a peak in low offset and low drift. I still fear a charge amplifier will be needed, since this is the most recommended for high impedance sources but it seems that the long cables somehow succeed to add noise if I use this kind of input preamplification (also an option to my instrument). Actually the feedback resistance would have to be as large as 110 Mohms and it needs special shielding. The low current noise information is very useful. Indeed there are far better op amps from the polarization current point of view.

It was very helpful for me to receive feedback from actual specialists.

Thanks again!

Best regards!
