Which parts/strategy do you recommend for isolation of ADI's 32 bits SAR ADC?
On behalf of Eric Benedict:
Which ADC are you interested in and what are your application requirements?
The LTM2893 could be a good solution for the LTC2508-32 which is configured with pin strapping.
The LTC2500-32 has features which require SPI write access, however it has some configurations which do not require the SPI configuration. The LTM2893-1 variant supports SPI write, but only under certain conditions/limitations. I am presently working on verifying the compatibility of the LTC2500-32 with the LTM2893-1.
