AK4621

24-Bit 192kHz Stereo Audio CODEC

GENERAL DESCRIPTION

The AK4621 is a high performance 24-bit CODEC that supports up to 192kHz recording and playback.

The on-board analog-to-digital converter has a high dynamic range due to AKM’s Enhanced Dual-Bit

architecture. The DAC utilizes AKM’s Advanced Multi-Bit architecture that achieves low out-of-band

noise and high jitter tolerance through the use of Switched Capacitor Filter (SCF) technology. The

AK4621 is ideal for Pro Audio sound cards, Digital Audio Workstations, DVD-R, hard disk, CD-R

recording/playback systems, and musical instrument recording.
