• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Note 15. PMVCM=PMDAC=PMAUX bits = “1”, PMHP=PMLO bits= “0”, LINL=LINR=RINL=RINR bits = “0”,
Note 16. For AC load
Note 17. Output voltage is proportional to AVDD voltage. Vout (typ) = 0.212 x AVDD [Vrms] @ 0dBFS
Note 18. PMVCM=PMDAC=PMHP=PMLO=PMAUX bits = “1” and HP-Amp output is off.
Note 19. All digital input pins including clock pins (MCLK, BICK and LRCK) except I2C and CSN/CAD0 pins are held
