This video highlights the difference between single-ended,
pseudo-differential, fully-differential, and true-differential inputs.
Additionally, it covers the difference between unipolar and bipolar inputs.
Finally, it discusses the difference between a switched capacitor input SAR
ADC and a SAR ADC with an internal buffer.
