AK4493SEQ Premium Audio DAC
Velvet Sound™ Technology meets 32-Bit 768kHz Stream – The Professional 2-Channel Audiophile DAC Choice for High-End Acoustic Architecture.
// High-Resolution 125dB Dynamic Range 48-Pin LQFP Portfolio
The Velvet Sound™ Acoustic Advantage
The AK4493SEQ represents a premier next-generation benchmark for high-fidelity audio system decoding requiring absolute dynamic warmth and ultra-low noise degradation. Engineered by AKM utilizing their patented Velvet Sound™ architecture, this 32-bit 2-channel stereo DAC chip balances high-density processing with massive power optimization. Housed in a low-inductive 48-lead LQFP outline package, it secures pure, deterministic signal paths supporting digital audio streaming master tracks without jitter hazards.
- 32-Bit premium stereo resolution capturing micro-scale acoustic textures
- Integrated OSR Doubler technology drastically reducing out-of-band noise profiles
- Six types of built-in customizable digital filters shaping perfect response curves
Key Performance Advantages
768kHz PCM & DSD512
Decodes high-resolution PCM inputs up to 768kHz and DSD direct inputs up to 22.4MHz, maintaining master tape fidelity loops smoothly.
125dB Wide Dynamic Range
Achieves an outstanding 125dB SNR combined with an ultra-low -115dB THD+N rating, shielding pure acoustics from localized system hiss.
Low-Power Envelope
Optimized for dynamic power-rail switching, reducing idle current draw significantly to suit advanced battery-powered playback hubs.
