DIGITAL AUDIO INTERFACE
AK4118A
192kHz 24-Bit DIR with 8:1 Selector, GPIO & DIT
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 AC­3 applications. The dedicated pins or a serial µP I/F can control the mode setting. The small package, 48pin LQFP saves the system space.
