Be recursive, you could use and amp-op to reduce the amplitude of the signal, and then mount it on a DC signal. Its not a elegant solution but it should work.
Very similar problem was discussed here some time ago ..
Take a look at: example.png
In your case:
Vr-->0v
Vref-->3.3V
All you need to do is to calculate values of R1, R2 and R3 ..
(you may need to include the input impedance of the ADC)
