Nuvoton has launched the NAU8421YG, a high‑quality 24‑bit stereo DAC targeting high‑end audio playback, professional recording, and industrial audio acquisition. It delivers 8Vpp differential analog output, 128dB SNR, and –99dB THD+N for maximum signal fidelity.

The chip runs on dual power supplies (3.3V digital I/O, 5V analog) with typical power consumption of just 40–50mW. It features an auto clock detection sequence for smooth start/stop and simplified integration. Control is via I²C, with pin‑configurable options and standalone hardware mode.

Key specs include 105dB PSRR at 1kHz (rejecting power supply noise), 140dB channel separation (eliminating crosstalk), and wide dynamic range. The QFN‑32 (5×5mm) package operates from –40°C to +85°C , suitable for both consumer and industrial equipment.

Ideal for replacing built‑in DACs in streamers, media players, audio interfaces, and mixing consoles.

ICgoodFind: The NAU8421YG combines excellent SNR, low distortion, and low power – a strong choice for high‑precision stereo conversion in pro audio and industrial systems.
