GENERAL DESCRIPTION
AK4584 is a high-performance 24-bit CODEC for 96kHz consumer audio and digital recording
applications. The on-board analog-to-digital converter has an impressive dynamic range, thanks in part
to AKM’s Enhanced Dual-Bit architecture. The DAC features the newly developed Advanced Multi-Bit
architecture and achieves low out-of-band noise and high jitter tolerance through the use of Switched
Capacitor Filter (SCF) technology. The AK4584 also has a S/PDIF-AES/EBU digital audio transmitter
(DIT) and a digital audio receiver (DIR) that are compatible with 24-bit, 192kHz formats. The AK4584 can
automatically detect NON-PCM bit streams like AC-3, MPEG and DTS. Either the ADC or the digital
audio input can be routed directly to the digital audio output. The AK4584 has an input Programmable
Gain Amplifier and is well suited for computer DAWs, MiniDisc, DVD-R, hard disk and CD-R
recording/playback systems.
