[AK4589]
MS0339-E-00
2004/09
GENERAL DESCRIPTION
The AK4589 is a single chip CODEC that includes two channels of ADC and eight 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 AK4589 has a dynamic
range of 102dB for ADC, 114dB for DAC and is well suited for digital surround for home theater audio.
The AK4589 also has the balance volume control corresponding to the Dolby Digital (AC-3) system.
The also has digital audio receiver (DIR) and transmitter (DIT) compatible with 192kHz, 24bits. The DIR
has 8-channel input selector and can automatically detect a Non-PCM bit stream. The AK4589 provides
a compatibility of hardware and software with the AK4588.
*Dolby Digital (AC-3) is a trademark of Dolby Laboratories.
