Signal conditioning for piezo sensors

Other Parts Discussed in Thread: TLV2771

Hi 

I have a piezo sensor, and its output is only around 1 millivolt. Is there any guidance about the circuit design for its signal conditioning and amplifier? as well as proper Ti amplifier?

Thanks

    Hello Rujie,

    See the following TI Applications Report:

    The report references the TLV2771 CMOS op amp, but If you decide you need an op amp having different capabilities we can help direct you to one.
