• Description: 24-bit Stereo Dac With Hp-amp & 2v Line-out
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta=25°C; AVDD, DVDD, HVDD, PVDD=2.7 ∼ 3.6V, TVDD=1.6 ∼ 3.6V; fs=44.1kHz; De-emphasis = “OFF”)
Note 20. The passband and stopband frequencies scale with fs.
Note 21. Delay time caused by digital filtering. This time is from setting the 16/20/24bit data of both channels to input
Note 22. DAC
Note 23. LIN
(Ta=25°C; AVDD, DVDD, HVDD, PVDD=2.7 ∼ 3.6V; TVDD=1.6 ∼ 3.6V)
Note 24. Except I2C and CSN/CAD0 pins. These pins have internal pull-up device, nominally 100kΩ.
