AK4366
Low Power 24-Bit 2ch DAC with HP-AMP
GENERAL DESCRIPTION
The AK4366 is 24bit DAC with built-in Headphone Amplifier. The integrated headphone amplifier
features “click-free” power-on/off, a mute control and delivers 50mW of power at 16Ω. The AK4366 is
housed in a 16pin TSSOP package, making it suitable for portable applications.
