AMC1100: AMC1100DUBR

Ansul Tyagi

Part Number: AMC1100

Hi,

I'm using AMC1100 analog isolator for current sensing application.

input side of the amplifier is connected between 5V and ground_1 and output side is connected between 3.3V and ground_2.

there is a voltage difference between ground! and ground_2

ground_2 is 70V above ground_1

Will AMC1100 work is such a configuration? what are the points to consider?

Hi Ansul,

yes the AMC1100 will work this way.

Hi Ansul,

The specification that defines the maximum voltage between GND1 and GND2 is the isolation working voltage, which is 1200Vdc for the AMC1100.

Thanks Kai!
