Hi Anirudra, Q1. The AVCC/AVSS much still be connected, but they do not need to be high-voltage. AVCC can be tied to 5V, AVSS can be grounded. Note that REF_CMP is not NC, it still should have the compensation capacitor connected to it. Q2. The low voltage LV_ADCs will still be mapped to 0V to 5V. The high-voltage inputs will still be mapped to -12.5V to 12.5V, even with the lower supplies. Thanks, Paul
