ak4420 AKM Semiconductor, Inc., ak4420 Datasheet - Page 6

• Manufacturer Part Number: ak4420
• Description: 192khz 24-bit Stereo ?? Dac With 2vrms Output
• Manufacturer: AKM Semiconductor, Inc.

(Ta = 25°C; VDD=CVDD = +4.5 ∼ +5.5V; fs = 44.1 kHz)
Note 11. The passband and stopband frequencies scale with fs(system sampling rate).
Note 12. Calculated delay time caused by digital filter. This time is measured from setting the 16/24bit data
(Ta = 25°C; VDD=CVDD = +4.5 ∼ +5.5V)
Note 13. The SMUTE pin is not included. The SMUTE pin has internal pull-down resistor (typ.100kΩ).
