Part Number: DRV2700

Dear Team,

 

Is it possible to support over 100kHz output with DRV2700?

If not, do you have any piezo driver supporting 100kHz output?

 

Best Regards,

Hirokazu Takahashi

  • Takahashi-san,

    Unfortunately, the output frequency of the DRV2700 is limited to frequencies below the 20KHz even with a low capacitive load as shown in picture below:

     For these particular cases where a high-speed frequency is required, we often recommend to use a high-speed operational amplifier. Our haptics drivers are limited to frequencies like the ones shown in the picture above.

    I would recommend to start a new thread in the high-speed amplifiers Forum. They can orientate you in order to get the conditions that you are looking for.

    Please let me know if you have additional questions or comments about this.

    Best regards,
