AK4118A

High Feature 192kHz 24bit Digital Audio I/F Transceiver

GENERAL DESCRIPTION

The AK4118A is a digital audio transceiver supporting 192kHz, 24bits. The channel status decoder

supports both consumer and professional modes. The AK4118A can automatically detect a Non-PCM

bit stream. When combined with the multi channel codec (AK4626A or AK4628A), 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.
