I have some question about HVI as follow:


How many input voltage range will be measure by ADC? 

  1. RatioL_HVI (2:1)
  2. RatioH_HVI (6:1)
  3. By pass divider


VHVI= -27 ~ +42V (in Table G-2. Absolute Maximum Ratings - High Voltage Input Pins - Port L)

What happen when i connect +15V to HVI pin with Ratio of 2:1, 6:1 or bypass?
