    Hi, Ulf,

    For the TLC320AIC22C, it lists both of these as 4Vpp. One is referenced on page 6, the other, page 13.

    I couldn't find this data for the AIC1110, but I did see reference to 4.54V on page 14 of the data sheet for the differential output voltage. This is for 32 ohms, for 150 ohms, you will get even more swing.
