CS4304S Overview

The CS4304S is a 4-channel, 32-bit resolution audio DAC supporting sample rates of up to 768 kHz. The CS4304S’s proprietary filtering adapts to preserve clarity and tonal accuracy across sample rates of 44.1 kHz to 768 kHz, creating a consistent sound that stays balanced independent to the content users are playing. Compared to alternative solutions that rely on specialized low-noise supplies, the CS4304S achieves 118 dB dynamic range without added BOM cost and complexity. Operating at 13 mW/ch, the CS4304S is optimized for high audio performance without compromising power efficiency or cost.
