What methods can be used for sampling an analog signal using a microcontroller?

Assuming the micro's internal ADC will have enough performance to do th job... What you'd usually do is setup one of the micro's timers to trigger the micro's ADC at the desired sample rate. Most ...

What methods can be used for sampling an analog signal using a microcontroller?

You need to use an ADC that either times its own conversions (like your I2S one -- but those aren't the only ones), or you need to use an ADC that accepts an external start of conversion pulse, and ...

What methods can be used for sampling an analog signal using a microcontroller?

Let me know if there's anything simpler or more effective I can do with regard to ADC sampling at a constant rate You don't need to restrict your choice of ADC to ones with an I2S interface. Most ...

Limit of daisy-chaining of multiple ADCs

That sounds extremely expensive; is there a reason to choose a single-channel ADC? There seem to be many options with multiple inputs (muxed or simultaneous sampling), in the same price even. As for ...

Limit of daisy-chaining of multiple ADCs

This should be perfectly feasible. The AD7685 is designed for this, and has an integrated sampling clock, meaning that the only limiting factor for you is the SPI clock rate. You need to allow for ...
