• Description: 3v 192khz 24bit ?? Codec
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta=25°C; VA=VD=3.0V; VSS=0V; fs=48kHz, 96kHz, 192kHz; Signal Frequency=1kHz; BCLK=64fs; Data=24bit
otherwise specified)
Note 4. This value is the full scale (0dB) of the input voltage. Input voltage is proportional to VA voltage.
Note 5. This value is the full scale (0dB) of the output voltage. Output voltage is proportional to VA voltage.
Note 6. When LOUT/ROUT drives some capacitive load, a 220Ω resistor should be added in series between
Note 7. For AC-load
Note 8. PSR is applied to VA and VD with 1kHz, 50mVpp. VCOM pin is connected to a 2.2µF electrolytic capacitor and
