GENERAL DESCRIPTION
The AK4368 is 24-bit DAC with an integrated PLL and headphone amplifier. The PLL input frequency is
synchronized to typical mobile phone clock frequencies. The AK4368 features an analog mixing circuit
that allows easy interfacing in mobile phone and portable communication designs. The AK4368 includes
a 3-D stereo enhancement circuit that operates with both the headphone amplifier and the stereo lineout.
The integrated headphone amplifier features “pop-free” power-on/off, a mute control, and it delivers
50mW of power into 16
. The AK4368 is packaged in a 41-pin BGA package, deal for portable
applications.
