AK4527B  
High Performance Multi-channel Audio CODEC  
GENERAL DESCRIPTION  
The AK4527B is a single chip CODEC that includes two channels of ADC and six channels of DAC. The  
ADC outputs 24bit data and the DAC accepts up to 24bit input data. The ADC has the Enhanced Dual Bit  
architecture with wide dynamic range. The DAC introduces the new developed Advanced Multi-Bit  
architecture, and achieves wider dynamic range and lower outband noise. An auxiliary digital audio input  
interface maybe used instead of the ADC for passing audio data to the primary audio output port. Control  
may be set directly by pins or programmed through a separate serial interface.  
The AK4527B has a dynamic range of 102dB for ADC, 106dB for DAC and is well suited for digital  
surround for home theater and car audio. An AC-3 system can be built with a IEC60958(SPDIF) receiver  
such as the AK4112A. The AK4527B is available in a small 44pin LQFP package which will reduce  
system space.  
*AC-3 is a trademark of Dolby Laboratories.
