GENERAL DESCRIPTION
The AK4112B is a digital audio receiver (DIR) compatible with 96kHz, 24bits. The channel status
decoding supports both consumer and professional modes. The AK4112B can automatically detect a
Non-PCM bit stream. When combined with an AK4527B multi channel codec, the two chips provide a
system solution for AC-3 applications. The dedicated pins or a serial P I/F can control the mode setting.
The small package, 28pin VSOP saves the board space.
*AC-3 is a trademark of Dolby Laboratories.
