1 [AKD44SA] AKD44SA Evaluation board Rev.0 for AK44 GENERAL DESCRIPTION The AKD44SA is an evaluation board for AK44, the 4bit 8ch D/A converter. The AKD44SA also has the digital audio interface and can achieve the interface with digital audio systems via optconnector or B connector. Ordering guide AKD44SA Evaluation board for AK44 (Cable for connecting with printer port of IBMAT compatible PC and control software are packed with this. This control software does not operate on Windows NT) FUTION Compatible with types of interface DIR with optical input and B input Direct interface with AC decoder by 0pin header 0pin header for serial control interface V V Regulator GND LOUT ROUT LOUT ROUT Output Buffer AK44 DIR AK4 Control Data 0pin Header B In Opt In LOUT AC ROUT 0pin Header Figure.
