Hi Wenting,

Sure we can check this out.

I do want to share though that we have another driver for ultrasonic lens cleaning (DRV2911) that is much smaller in size than DRV2901.

Hi Wenting,

I've reviewed the documents and got two questions.

Do you know what is the impedance response of the customer's lens cover? The LC filter and I/V sense path components at the output require modifications based on the specific lens cover design.

Moreover, we have another driver for ultrasonic lens cleaning (DRV2911) that is much smaller in size and also much lower cost than DRV2901. Any reason why the customer chose DRV2901?

Thanks

Hailong
