DRV425EVM: Graph response

Ray Vincent Aranzaso

Part Number: DRV425EVM

Hi,

Good Day. I have a customer who is wondering if we have a response graph available for the DRV425EVM up to a few kHz and a noise graph. Also, looking at this document, https://www.ti.com/lit/ug/slou410b/slou410b.pdf, if section 4.3 equation for the field is valid at AC. Please advise. Thank you very much.

Best Regards,

Ray Vincent

Ray,

We do not have the noise graph but you can see this post with an Excel that will give you what you want with regard to noise. The field equation should be valid for all the field, but to verify please give me the equation you are looking at. Keep in mind that if you are measuring field from a current in a conductor the eddy currents will cause the distribution of currents to change and therefore how the field is seen. This will change the field seen close to the conductor. If they are using it for a different application be aware if there is any change from the source of the field.
