Part Number: DRV2667
Other Parts Discussed in Thread: DRV2700

Dear, TI support team

My cusomer is searching part that can drive piezo buzzer.

Currently, we are reviewing DRV2667. But we need to drive frequency from 2kHz to 3kHz.

Can DRV2667 support to drive it?

Frequency vs. output voltage waveform of DRV2700 is available that.

Please recommend suitable part.

Thanks.

Hi MJ,

Yes the DRV2667 has similar bandwidth to the DRV2700 so it can support 2kHz to 3kHz operation.

Hi, Jeff

Can DRV2667 receive single-ended signal(negative itput=GND) to Analog input ports?

Thanks.

Hi MJ,

Yes the analog inputs can be operated in single-ended mode. The figure below is from the DRV2700 datasheet but it works the same.
