At 500k samples per second this is a fast 8-bit converter — suited for digitising high-frequency sensor bursts, current-sense waveforms, or level-shifted analog signals where 8 bits of resolution is enough.
It has two single-ended analog inputs selected through an internal mux. The input configuration is single-ended, not differential.
Yes, the reference type is external. There is no internal bandgap reference — the designer must supply a clean VREF to set the ADC's full-scale range.
