[AK4371] AK4371 DAC with built-in PLL & HP-AMP The AK4371 is 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 The AK4371 is packaged in a 32-pin QFN 4mmx4mm package, deal for portable applications.
