Currently having an issue where the SP720APP IC will not clamp an analog input voltage to 3.33V.
Here is a schematic of how the circuit is wired. VCC is 3.3V coming from an arduino. The analog inputs are 0-5V and then using a voltage divider a 0-3.3V signal is output. The SP720APP is used to protect the microcontroller analog input pins. The circuit is to be used with a teensy 3.2 where inputs above 3.3 is not allowed. The Arduino is being used to test if the SP720 will work.
