AK4620B
24-Bit 192kHz Audio CODEC with IPGA
GENERAL DESCRIPTION
The AK4620B is a high performance 24-bit CODEC that supports up to 192kHz record 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 AK4620B has
an input Programmable Gain Amplifier and is ideal for Pro Audio sound cards, Digital Audio Workstations,
DVD-R, hard disk, CD-R recording/playback systems, and musical instrument recording.
