GENERAL DESCRIPTION
The AK4370 is a 24-bit DAC with headphone amplifier. The AK4370 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 AK4370 is packaged in a 24-pin QFN (4mm×4mm) package, ideal for portable applications.
