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

16Ω. The AK4365 is housed in a 20pin QFN package, making it suitable for portable applications.
