piezo driving method

[ljy4468]

Hi all,

I have a question about drivng method of piezo.

Some manufacturer provide opamp driving method while some provide full-bridge driving method.
So what is the difference of driving method between them?

Thanks in advance.

A full bridge driver will supply twice the Vcc p-p voltage to the piezo and can be used at high power levels (> 1W). An opamp can only deliver Vcc p-p V to the sensor and is for low power (< 1W)
