CN0336: Where can I find a solution for a receiver in a 4-20mA current loop sensor application?

I’m currently searching for ICs which act as a receiver in a current-loop
sensoring application. It should have a SPI Interface.
(something like the AD421, but for the other side of the loop (ADC side instead
of DAC).


We have a reference design CN0336 for a 4 mA to 20 mA single supply analog to
digital conversion application with
Isolated SPI interface. This circuit could be used as a receiver in a current
loop sensing application.

You can find out more and download the schematic, documentation, gerbers, bill
of materials and more at the following web page:

We can also provide the hardware in a PMOD form factor, part number:
