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.
