AK4534  
CODEC with MIC/HP/SPK-AMP  
16Bit  
DS  
GENERAL DESCRIPTION  
The AK4534 is a 16bit stereo CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier and  
Speaker-Amplifier. Input circuits include Microphone-Amplifier and ALC (Auto Level Control) circuit. And  
output circuits include Headphone-Amplifier and Speaker-Amplifier. Therefore the AK4534 suits a PDA.  
The package of AK4534VQ is 48pin LQFP and the package of AK4534VN is 52pin of QFN. A new system  
can be smaller board area than a current system is composed of 2 or 3 chips.
