AK4586

[AK4586] AK4586 Multi-channel Audio CODEC with DIR GENERAL DESCRIPTION The AK4586 is a single chip CODEC that includes two channels of ADC and six channels of DAC. The ADC outputs 24bit data and the DAC accepts up to 24bit input data. The ADC has the Enhanced Dual Bit architecture with wide dynamic range. The DAC introduces the new developed Advanced Multi-Bit architecture, and achieves wider dynamic range and lower outband noise. The AK4586 also has a digital audio receiver (DIR) compatible with 96kHz, 24bits. The AK4586 can automatically detect a Non-PCM bit stream. The digital audio output can be selected from the ADC output or the digital input. Control may be set directly by programmed through a separate serial interface. The AK4586 has a dynamic range of 100dB for ADC, 106dB for DAC and is well suited for digital surround for home theater and car audio. The AK4586 also has the balance volume control corresponding to the AC-3 system. The AK4586 is available in a small 44pin LQFP package which will reduce system space. *AC-3 is a trademark of Dolby Laboratories.
