Note 7. Maximum Input Voltage of LIN/RIN pins is proportional to AVDD voltage. Since the internal feedback resistor

is 20k

Ω±30%, the external resistor should determine that the value does not exceed the maximum input voltage.

Note 8. The gain is inverse proportion to external input resistance.

Note 9. PGAL4-0=PGAR4-0= 0dB

Note 10. LPGA4-0= 0dB

Note 11. PMVCM=PMCP=PMDAC=PMHP bits = “1”, PMLO=PMAUX bits= “0”, LINL=LINR=RINL=RINR bits =

“0”, ATTL7-0=ATTR7-0= 0dB, PGAL4-0=PGAR4-0= 0dB.

Note 12. Output voltage is proportional to AVDD voltage. Vout (typ.) = 0.303 x AVDD [Vrms] @ 0dBFS

Note 13. PMVCM=PMCP=PMDAC=PMLO bits = “1”, PMHP=PMAUX bits= “0”, LINL=LINR=RINL=RINR bits =

“0”, ATTL7-0=ATTR7-0= 0dB, LPGA4-0= 0dB.

Note 14. Output voltage is proportional to AVDD voltage. Vout (typ.) = 0.606 x AVDD [Vrms] @ 0dBFS
