CC1310: ADC not working as expected

Part Number:CC1310

Hello Ti,

I'm working with adcsinglechannel example, if i give 0.5voltage in ADC-1 DIO24, the converted value it is showing as 2023 and voltage as 2147376microvolt.

Expected value should be 620.

Can you explai why I'm getting these values?

Thanks and Regrads,
