Modification on a sine wave before ADC
Anything with gain and offset will work to match load requirements and CMRR.

Av = 2.2/10
Offset = 2.2/2 = 1.1

Details can be worked out easily with more info.

I might suggest HPF with series C and Rs = 78k then shunt Rp = 22k to 1.1V reference derived from Vdd or Vref on board.
