Tool/software:

Dear Specialists,

My customer is interested in DRV2700EVM-HV500 and has a question.

I would be grateful if you could advise.

---

I would like to use DRV2700EVM-HV500 and drive150V for piezo bulb.

In this configuration, the accuracy of the output voltage depend on the reference voltage device inside.

Could you please let me know the accuracy of internal reference of DRV2700?

I could not see the datasheet.

I appreciate your great help in advance.

Best regards,

Shinichi

Hi Shinichi,

I looked through our validation data and this was not measured. It should be considered fixed to 1.3V.

HI Kelly,

Thank you for your reply.

I understand internal reference voltage is not measured.

I think it is a little bit strange, but I accept.

When the customer has an additional question, I consult you again.

I appreciate your great help and cooperation.

Best regards,

Shinichi
