Resolved! STM32G0B0KE Input voltage range when using Vrefint

I'm trying to decide what G0 STM32 part to use on a brand new design. One of the requirements is to have six channels of ADC. The datasheet talks about the range of input voltage being Vssa <= Vin <= Vref+. However, on the 32-pin part, there is no Vr...
