« on: November 29, 2019, 05:16:12 pm »
Hi ,
i wan't to isolate a analog voltage the first circuit that i found is the HCNR201 wich have a very low  Transfer Ratio that is a very critical parameter for a good analog isolation circuit , the problem is that i didn't find this component in my country , so what are the alternative for a good analog isolation ?

HCPL7800 and variety (there's a whole product family of such couplers available from broadcom).
It's a different thing than the HCNR201, easy to use but noisy.
Safety devices hinder evolution
