Single ended Line-level solution:
Apply a DC bias level on the non-inverting input and input the signal through a coupling capacitor on the inverting
input. C4 and R4 determine the HP-filter characteristics, while C5 and R5 determine the LP-filter characteristics.

3.1.6.2 AFMS path
An application using the analog audio interface must re-reference the AFMS-signal from AGND to its own internal
BIAS. The figure shows a differential implementation. C1 is chosen to create the correct HP frequency response.
R1 and R2 determine the gain, and C2 and R2 determine the LP frequency response.
