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 P I/F can control the mode setting.The small package, 48pin LQFP saves the system space.
