AMC1300: IMRR of AMC1300

Part Number: AMC1300
Other Parts Discussed in Thread: ISO124,

Hi all,

in search of a suitable isolation amplifier I tested the AMC1300B.

This part showed a surprisingly smooth output signal, compared to the Iso124/224.

Unfortunately I cannot find the IMRR in the datasheet, but I hope it matches the IMRR of the Iso124/224.

Has anyone a source for this parameter.

Thank you.

Hi again Rolf,

Please refer to the post from last week on the ISO124, the same applies the AMC1300. I'll request to get IMRR included in future datasheets.

Hi Tom,

I guessed that the isolation technology is the same for both devices.

It only struck me that the output signals of the AMC1300 were so smooth.

But it's perhaps due to the low input voltage range.

At any rate I'll test the AMC more extensively and when the IMRR is beyond 120dB it will become my favorite.

Thank you.

Rolf
