Asahi Kasei Microdevices AK4112A
The AK4112A is a digital audio receiver (DIR) compatible with 96kHz, 24bits. The channel status decoding supports both consumer and professional modes. The AK4112A can automatically detect a Non-PCM bit stream.GENERAL DESCRIPTION
When combined with an AK4527 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 VSOP saves the board space. *AC-3 is a trademark of Dolby Laboratories.FEATURES
