Hello,

I was wonder if the isolated amplifier ISO224BDWVR supports DC signal?

Thanks,

Hi Devid,

Yes, the ISO224 supports signals from DC up to the AC bandwidth limits that have been copied below. We are curious if you saw something in the datasheet that made you think otherwise.

Thank you for your reply.

The datasheet does not speak about DC voltage at all.

Does it mean that given a constant DC voltage at the input side of the isolator, the voltage at the output side of the isolator shall hold remain constant?

You're welcome, and understood. Yes, the transfer function applies for signals from DC up to the small-signal bandwidth of the product. All of the datasheet DC specifications (offset, gain error, etc. ) are measured with DC test signals.
