ASAHI KASEI
AKD5356 is an evaluation board for the portable digital audio 20bit A/D converter with Pre-Amp and
Analog Volume. The AKD5356 includes the analog input circuits (LINE and Pre-Amp) and also has a
digital interface transmitter. Further, the AKD5356 can evaluate direct interface with AKM's D/A converter
evaluation board.

  • Page 3 PORT1 (DIT) is used. On board DIT (AK4103) converts A/D data to an audio biphase signal, which is output through optical connector (TOTX176). It is possible to connect AKM’s D/A converter evaluation boards or the digital-amplifier that equips DIR input etc. Nothing should be connected to PORT3.
