DRV425EVM: Design help recommendation

Part Number: DRV425EVM
Other Parts Discussed in Thread: DRV425

Hi Experts,

Good day. Seeking your assistance on this query:

hello i have purchases the DRV425evm, i am using it in a project to detect the magnetic field of cables used in residental homes. the microcontoller i am using is the arduino uno r3 and it has a insufficents ADC i was wondering based off the other questions which is recommended as i would like to use it for digital filtering and the DRV425evm is being used in a differential mode. for the filtering i would need to isolate the 60hz signal and i understand a bandpass filter would be best for this application however signal processing is not my strong suit, what would you recommend? meaning i have two. do you think you can assist me with this?

Thank you.

Regards,
Archie A.

Hello Archie,

I can assist with the use of the DRV425 but digital filtering would or signal processing is more of a question for the signal processing team. They are not using our processor so I don't know how much that team can help.

For use of the 2 DRV425 the user need to be aware about placement and the fields seen by each DRV425. If placed correctly one could use one voltage that combines the signals as mentioned in this document.

Hello Javier,

I created a separate thread for this:

Would you recommend microcontroller for digital filtering and the DRV425evm is being used in a differential mode? - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums

Thanks again.
