Multiple i2c devices on single isolator?

[mayor]

Hi,

I'm considering building a carrier board for Atlas Scientific amplifier boards (used to read ORP, pH and temperature), similar to their board: https://atlas-scientific.com/files/Wi-Fi-Pool-kit-setup-guide.pdf. I plan on using my own long-range microcontroller board instead of the Huzzah board.

Apologies for the quality of the image, but this basically shows 3 isolated i2c boards and one non-isolated. They use https://www.analog.com/media/en/technical-documentation/data-sheets/ADM3260.pdf for isolation.


Each is along these lines:


Besides the fact that they use the enable/disable pin on the isolator to turn each of the sensors on and off, my question is: could you use a single isolator and tie the i2c bus of each sensor (they all have separate addresses) together instead of using 3 isolators?

Thanks!
