*The relations of ”VSS= 0V” and “VDD= VDDO” must be maintained.

*VSS(SSOP10:Pin No.6,10, QFN20:Pin No.9,10,16,17) should be connected at a nearest point to the IC.

*VDDO(SSOP10:Pin No.8, QFN20:Pin No.13) should be connected at a nearest point to the IC.

*MUTE(SSOP10, QFN20:Pin No.4) and STBY(SSOP10:Pin No.5, QFN20:Pin No.7) must be connected

to VDD, when these pins are not used.
