Note 1. All input pins except analog input pins (MIN/LIN3, LIN1, RIN1, LIN2, RIN2, RIN3, RIN4, and LIN4 pins)
should not be left floating.
Note 2. All analog input pins (MIN/LIN3, LIN1, RIN1, LIN2, RIN2, RIN3, LIN4, and RIN4 pins) should supply signal
via AC-coupling capacitor.
Note 3. Analog output pins (HPL, HPR, LOUT, and ROUT pins) except speaker output (SPLP, SPLN, SPRP and SPRN
pins ) and headphone output in Pseduo cap-less mode (HPL and HPR pins) should deliver signal via AC-couplling
capacitor.
Handling of Unused Pin
The unused I/O pins should be processed appropriately as below.
