[AK4621] 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.
