DRV421: DRV421

Hello Hironari,

Thank you for your post. 

Can you please provide more context on your application?

Is there a specific reason you went to this Integrated Fluxgate Magnetic Sensor IC?

What is the level of current that you will be measuring through the primary current conductor?

Answering these questions will help me with choosing the right device for your application. 

Best Regards, 

Joe

Joe,

Thank you very much your reply. And sorry to late reply.

Ths is more likely PGA300 since I couldn't find in your signal conditioning list. (No more PGA300?)

The sensor consist half bridge. So I need the conditioning IC with more than 10kHz responce.

I apprciate if you could provide me any product if availavle.

Please let me know if you need any farther information.

BEST REGARDS,

Hironari

Hello Hironari, 

I believe we still have the PGA300: PGA300 data sheet, product information and support | TI.com

Would you like me to connect you with this team?

Best Regards,

Joe,

Thank you very much. Please I need to see more detail specification for PGA300. Or other device information if available.

But I was wondering why there was no PGA300 on your list.

BEST REGARDS,

Hironari

Hello Hironari, 

The reason why devices such as the DRV421 are not paired with the PGA300 is that these are very different devices. 

The DRV421 is a fluxgate current sensor and the PGA300 is a Signal Conditioner and Transmitter for Pressure Sensors.

Here is another E2E post that goes through some guides and app notes for the PGA300: (3) PGA300: Current consumption (maximum) - Sensors forum - Sensors - TI E2E support forums

I hope this helps, 

Joe
