In the last video we saw that using a resistor and Schottky diode was effective at protecting the ADC, but impacted the performance of the system. Furthermore, the power rating of the resistor required for current limiting was high which is inconvenient because the cost and PCB board area is high. In this section we show an improved solution that can be used in some cases to both improve AC performance while using a current limiting resistor with a lower power rating.
