AMC3301-Q1: AMC3301-Q1

Hi Ku,

Your schematic looks correct.  Can I ask you why you choose the AMC3301 over the AMC3311?  The AMC3311 has higher input impedance and offers a 0-2V input range specifically for voltage measurement applications.  You would not need the R90 resistor with the AMC3311 device.

Hi Tom,

Originally i plan to use AMC3301 device to perform current & voltage sensing for my design.

And i use Isolated Amplifier Current Sensing Excel Calculator Rev A & Isolated Amplifier Voltage Sensing Excel Calculator Rev B 

for reference design.AMC3311 was not in the device selection table, so it not being choose.

Thank you.

Best regards,

Ku

Hummm...it should be there, did you look at the Single Ended option?

Hi Tom,

No, i select the differential type device.

The AMC3311 device was not in the table.

Best regards,

Ku
