Low Power & Small Package 16bit  
CODEC  
GENERAL DESCRIPTION  
The AK4554 is a low voltage 16bit A/D & D/A converter for portable digital audio system. In the AK4554,  
the loss of accuracy form clock jitter is also improved by using SCF techniques for on-chip post filter.  
Analog signal input/output of the AK4554 are single-ended, therefore, any external filters are not required.  
The AK4554 is suitable for portable digital audio system, as the AK4554 is low power dissipation and a  
small package.  
FEATURES  
† HPF for DC-offset cancel (fc=3.4Hz)  
† Single-ended ADC
