AK4114

High Feature 192kHz 24bit Digital Audio Interface Transceiver

GENERAL DESCRIPTION

The AK4114 is a digital audio transceiver supporting 192kHz, 24bits. The channel status decoder

supports both consumer and professional modes. The AK4114 can automatically detect a Non-PCM bit

stream. When combined with the multi channel codec (AK4527B or AK4529), the two chips provide a

system solution for AC-3 applications. The dedicated pins or a serial µP I/F can control the mode setting.

The small package, 48pin LQFP saves the system space.

*AC-3 is a trademark of Dolby Laboratories.
