[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. FEATURES □ 24-bit 2-channel ADC - Full Differential Inputs - Selectable Digital Filter 1. ADC Sharp Roll Off Filter (GD=39/fs) Passband: 0 ~ 21.
