AK4367  
Low Power 24-Bit 2ch DAC with HP-AMP & Output Mixer  
GENERAL DESCRIPTION  
The AK4367 is 24bit DAC with built-in Headphone Amplifier. The AK4367 features an analog mixing  
circuit that allows easy interfacing in mobile phone and portable communication designs. The integrated  
headphone amplifier features “pop-free” power-on/off, a mute control and delivers 50mW of power at  
16. The AK4367 is housed in a 20pin QFN package, making it suitable for portable applications.
