Dear expert,
attach my voltage sensing design using AMC3301 device.
My input power range Vdc = 40V to 160V.
below the data measure during input power =80V.
Is my design OK?
Thank you.
Best regards,
Ku
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
Hi Tom,
No, i select the differential type device.
The AMC3311 device was not in the table.
