Electronic – What analogue input voltages does this ADC understand


I have a 14-bit ADC for which I do not know what the "accepted input voltage" is.

The datasheet specifies that there are "out-of-range" signals, but I cannot find what the range is. What is the range of my ADC?

From what I can understand from the datasheet, the input voltage can be defined from 1V p-p to 2V p-p

Span = 2 × (REFT − REFB) = 2 × VREF -- (From page 17)

VREF = 0.5 × (1 + R2/R1) -- (From pages 20/21)
