AK4365

DAC with built-in PLL & HP-AMP

GENERAL DESCRIPTION

The AK4365 is 20bit DAC with built-in PLL and Headphone Amplifier. The PLL input crystal frequency is

matched to typical mobile phone clock frequencies. The AK4365 features an analog mixing circuit that

allows easy interfacing in mobile phone and portable communication designs. The integrated headphone

amplifier features “click-free” power-on/off, a mute control and delivers 10mW of power at 16W. The

AK4365 is housed in a 28pin QFN package, making it suitable for portable applications.
