Hii my name is aied ,a hardware engineer
i am designing a circuit for voltage measuring purpose , my input comes from CT (current transformer ) with values of 0 to 100mA .and i use an opamp to transform the current to voltage
so the input to my device is current not voltage !!
i need to isolate my device from the environment and i came across your isolation IC products
and my question is, if i have an current input as i described above ( that is not a digital communication line ) what iso isolation chip i can use ?
a will also say that after converting the current to voltage i will get 3.3v DC max using the op-amp
but i need to put the op amp after the isolation chip
in other words do you have a chip that can deliver current from input pin to output pin that is also isolated ?
i can use the op-amp circuit to convert the current to voltage and then connect it to the isolation chip but then i will run the risk of my op-amp circuit is not protected .
i will be very thankful for your help
