In the adc papers, I often see the words like "the input range is 1.5Vpp".
But what does it exactly mean? (For example: 1)the single supply voltage is 3v
2)the double supply voltage are
-1.5v、1.5v)

it means volts-peak-to-peak

THe Vpp means voltage peak to peak. If input range is 1 V peak to peak then you can either use the voltage from 0 to 1 V or also from -.5V to +5V..

Added after 18 seconds:

THe Vpp means voltage peak to peak. If input range is 1 V peak to peak then you can either use the voltage from 0 to 1 V or also from -0.5V to +0.5V..

it means peak to peak . if you use oscillograph to do test .and you want to get a pulse, you can see this parameter.

Do you mean that vpp has nothing to do with the supply voltage??
And if we set the input range to be 2vpp, then it only means a range and can't get the exact max and min voltage value??
