AK4205

Ultra Low Noise and Distortion Headphone Amp with Analog Switch

1. General Description

The AK4205 is a stereo headphone amplifier corresponding to high resolution with built-in analog switch

for Hi-Fi mobile. The AK4205 achieves industry’s leading level ultra-low noise and ultra-low distortion

characteristics (THD+N = -118dB).

The AK4205 is available in a small 36-pin QFN package. It can save the mounting area of the board by

including resistors for gain adjustment and low-pass filter.

Application:

 Smartphone

 Portable AMP

 Digital Media Player

 USB DAC
