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.
