AK4113
192kHz 24bit DIR with 6:1 Selector
GENERAL 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 µP or pin strapping (parallel mode). It is packaged in a
space-saving 30-pin VSOP.
* Dolby Digital is a trademark of Dolby Laboratories.
