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
