Can NAFE73388 be used with ICP accelerometer?

I see NAFE73388 product, which has a current excitation.

I wonder if it can be used with an ICP accelerometer (by PCB, CTC, ...) that needs a current excitation of 5 mA to polarize itself around 12 V (nominal).

On the same two wires, then the Anlog Input circuit must be able to read voltage.

Hello Ernesto,

Unfortunately the NAFE73388 cannot reach 5 mA, we are able to reach 2.5 mA. In the near future we may have a single channel product capable of satisfying the request. I have forwarded your contact details to our product group in Italy so they can share with you more details about this product by email.

BRs, Tomas

Thanks.
Do you mean that if the accelerometer can be polarize with 2.5mA only, the NAFE73388 is ok for this usage scenario?
What do you mean with "a single channel product capable of satisfying the request"? A new NAFE with only 1 channel?

Thank you for having shared my contact with the Italian team.
