AK4116

ASAHI KASEI [AK4116] AK4116 Low Power 48kHz Digital Audio Receiver GENERAL DESCRIPTION The AK4116 is a low power S/PDIF AES/EBU receiver supporting resolution up to 24-bit. The integrated channel status decoder supports both consumer and professional modes. The AK4116 can automatically detect a Non-PCM bit stream. Combining the AK4116 with a multi-channel codec such as AKM’s AK4527B or AK4529 can create a complete AC-3 system. Mode settings can be controlled via microprocessor serial interface. The small 20pin QFN package saves board space. *AC-3 is a trademark of Dolby Laboratories.
