AD1974 differential audio input impedance

Hi All,

 

Is there any differential impedance requirement (like 100 Ohms) that needs to be followed in the PCB layout while routing the audio inputs to AD1974 ADC? Our circuit is similar to AD1974 EVM where OP275 converts single ended to differential audio and this is fed to AD1974 inputs.

Shareef
