Hi,
I am re-opening this case again.
Our design is to use 8 individual Digital Isolator's ( ISO7341C ) for the Channel to channel isolation.
1. Do you have any idea about the SPI load driving capability?
2. What is the maximum loading to SPI line…
Hi Luis,
You can choose resistor values based on the available voltage that you want to down convert to 5V/3.3V. If basic isolation is sufficient, you could use ISO7340C. Based on flow directions of signals, any of ISO7340C, ISO7341C, ISO7342C should…

Hi Kuo,
Unlike Opto Isolators, TI Isolators have totem-pole outputs which can both source and sink currents. These currents are generally limited to a few mA for digital isolators, for example, ISO7341C can source/sink output current of ±4mA. I hope…

Hi Frank,
For DC offsets, we're recommending our new digital isolator family, ISO734x. ISO7342C and ISO7341C/FC are planned to be released in 4Q14. Preview datasheet is attached.

Hi Tom,
Thanks for your reply! Just wondering why you suggest this option over say the AMC1100 option or Fluxgate sensor? Thank you for your reference on synchronising sigma-delta measurements.
I have come up with some potential options. I would really…
