I'm sorry for my carelessness and thanks for your help!

For people such me:

BAV99W switching diodes are primarily used as diode clamps. If you expect to see accidental higher voltages at the INN, INP, DETP and DETM lines, it is recommended to use clamp diodes to supply and ground to protect the AFE44xx. For battery operated systems this might not be necessary.
