  asahi kasei [AKD4341-SB] 1 2007/03 general description AKD4341-SB is an evaluation board for ak4341 (192khz sampling 24bit ? dac). AKD4341-SB has a digital audio interface (ak4113) of optical or coax input and can easily achieve the interface with digital audio system. therefore, it is easy to evaluate the sound quality of ak4341.  ordering guide AKD4341-SB ---- ak4341 evaluation board function  on-board digital audio interface.
