[AK4112B] AK4112B High Feature 96kHz 24bit DIR 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 uP I/F can control the mode setting. The small package, 28pin SSOP saves the board space. *AC-3 is a trademark of Dolby Laboratories.
