AK4343  
Stereo DAC with HP/RCV/SPK-AMP  
GENERAL DESCRIPTION  
The AK4343 is a stereo DAC with a built-in Headphone-Amplifier, Receiver-Amplifier and 1.2W output  
Speaker-Amplifier. The AK4343 features analog mixing circuits and PLL that allows easy interfacing in  
mobile phone and portable A/V player designs. The AK4343 is available in a 32pin QFN, utilizing less  
board space than competitive offerings.
