Description

The AK4113 is a 24-bit stereo digital audio receiver that supports sampling rates up to 216kHz. The channel status bits decoder supports both consumer and professional modes. The AK4113 automatically detects non-PCM bit streams such as Dolby Digital, MPEG etc. When combined with the multi channel codec (AK4626 or AK4628), the two chips provide a system solution for Dolby Digital applications.Control of AK4113 is achieved though a P or pin strapping (parallel mode). It is packaged in a space-saving 30-pin VSOP.
