Part Number: FDC1004-Q1

Dear all,

Can we set the assignment of shield 1/2?

* For example, assigning shield 1 to CH1/2/3 and shield 2 to CH4.

And can we set the use of shield?

* For example, assigning shield 1 to CH1, assigning sheld 2 to CH2, and CH3/4 is not assigned to any shields.

Hello Yamamoto-san,

Please refer to Page 10-11 of the datasheet. The use of shields depends on the type of measurement (single-ended vs differential).

Hello Yibo-san,

Thank you for your reply.
I will use this with single-ended. And I read datasheet, but I did not understand clearly...
In this case, all channel is assigned to shield 1? Can't I change assignment like previous example?

Hello Yamamoto-san,

Sorry your follow-up question slipped through our radar because the post had been closed.

In single-ended mode, the two shields are internally shorted.

If you have additional questions, please feel free to start a new thread.

Regards,
Yibo
