GENERAL DESCRIPTION
The AK4371 is a 24-bit DAC with an integrated PLL and headphone amplifier. The PLL input frequency is
synchronized to typical mobile phone clock frequencies. The AK4371 features an analog mixing circuit
that allows easy interfacing in mobile phone and portable communication designs. The integrated
headphone amplifier features “pop-noise free” power-on/off, a mute control, and it delivers 40mW of
power into 16
Ω
. The AK4371 is packaged in a 32-pin QFN (4mm×4mm) package, ideal for portable
applications.
