  Brian Jadus The ideal isolator for an analog-to-digital converter (ADC) is
  one that is invisible. It manages all the control and data signals,
  maximizes the sampling rate and minimizes the effects of
  jitter on SNR performance. The LTM2893 ВµModule isolator
  achieves these goals for ADCs with SPI interfaces, in the
  1Msps range, and supports a 6000VRMS isolation rating.
  Reading data from high resolution successive approximation register (SAR) analog-to-digital converters
  through a digital isolator is limited with more traditional options. When reading from a serial peripheral interface (SPI) most high speed digital isolators
  max out at 25MHz, with a few specialty devices
  operating up to 40MHz. The LTMВ®2893 reads data
  at up to 100MHz, is flexible, and handles multiple
  ADCs solving the timing issues and limitations of
  standard digital isolators interfacing to SAR ADCs. …
