5. All audio input signals supplied differentially to the CS3511.
6. See
7. dBi is referenced to the input signal amplitude resulting in the specified output power at THD+N<1%. See
8. All audio input signals supplied single ended to the CS3511 with the negative input terminated to GND
9. Input impedance is measured between the positive (INx+) and negative (INx-) input pins of the CS3511.
10. See
