DRV8800: Can these be used to drive a piezo at around 50kHz?

Part Number: DRV8800
Other Parts Discussed in Thread: DRV8801

Hello. I'm trying to design a miniature device that uses a piezo-pump that needs an alternating driving signal of +-10V and 20 mA, at 49 kHz.

Can the DRV880X series be used for this purpose? Keeping the Enable PIN on, and shifting the PHASE of the output at the required frequency? Take into acount that there would be no inductive load. 

I was going to design my own H-Bridge, but this IC is very small and it has some features that interest me.

    Hi Manuel,

    Based on the information provided, the DRV8800 or DRV8801 can be used for the purpose. The device can drive almost any load as long as the current does not exceed the overcurrent level, and the device operates within the rated specifications.

    If the load acts like a capacitor, there could be possible issues with overcurrent.
