You had a slide that mentioned Buffered vs Unbuffered ADC, how do we know which is which? Is that stated in the datasheet?

  • Every datasheet has a block diagram that showcases the main blocks inside the ADC architecture. If the ADC of interest has a buffer, it will be shown in that block diagram. Also, a clear example in the application section should highlight how to setup the Common Mode for the ADC so there will be no surprises.
