AK4490REQ Premium Audio DAC
Velvet Sound™ Architecture meets 32-Bit High Resolution – The Professional 2-Channel Stereo DAC Choice for Audiophile Sound Systems.
// High-Fidelity 120dB SNR 48-Pin LQFP Layout Portfolio
The Velvet Sound™ Audio Advantage
The AK4490REQ represents a premier FLAGSHIP benchmark for high-resolution digital audio system decoding requiring absolute acoustic transparency and minimal out-of-band noise profiles. Engineered by AKM under their renowned Velvet Sound™ architectural framework, this 32-bit 2-channel stereo converter optimizes localized wave coplanarity. Housed in a standard 48-lead LQFP outline package layout, it secures pure, deterministic signal routing paths supporting ultra-dense audio streams without data jitter hazards.
- 32-Bit stereo resolution capturing fine-grained structural musical details
- Integrated low-distortion Switched Capacitor Filter (SCF) architecture
- Five types of built-in customizable digital filters optimizing frequency phase loops
Key Performance Advantages
768kHz PCM & DSD256
Decodes ultimate master-tape streams effortlessly, processing high-density PCM inputs up to 768kHz and raw DSD up to 11.2MHz lines.
120dB Dynamic Range
Achieves an ultra-clean 120dB Signal-to-Noise Ratio combined with a low -112dB THD+N rating, shielding circuits from background analog hiss.
Low Power Envelope
Engineered with optimized power-on-reset and supply rails, heavily dropping dynamic thermal dissipation indices across multi-channel arrays.
