Notes:
5. All audio input signals supplied differentially to the CS3511.
6. See Figure 5 on page 18.
7. dBi is referenced to the input signal amplitude resulting in the specified output power at THD+N<1%. See
“Parameter Definitions” on page 22 for more information.
8. All audio input signals supplied single ended to the CS3511 with the negative input terminated to GND
through an impedance matching circuit as described in Section 4.1 on page 13.
9. Input impedance is measured between the positive (INx+) and negative (INx-) input pins of the CS3511.
10. See Section 4.2 “Dynamic DC Offset Calibration” on page 13.
