AK4371 - DAC

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.

Key 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 16Ω. The AK4371 is packaged in a 32-pin QFN (4mm×4mm) package, ideal for portable.
