Uninterested in noisy, distorted audio or tough system setup? Discover a resolution that turns digital indicators into clear, exact analog output with minimal effort.
Changing digital audio to wash, correct analog indicators may be difficult, particularly in methods the place low distortion, excessive dynamic vary, and minimal crosstalk are essential. The NAU8421YG from Nuvoton addresses these points for audio engineers, system designers, musicians, and industrial measurement purposes by offering high-quality, low-noise analog output from digital sources.
The NAU8421YG is a 24-bit stereo DAC providing 8 Vpp differential analog output, 128 dB signal-to-noise ratio (SNR), and -99 dB complete harmonic distortion plus noise (THD+N). This ensures exact audio replica for computer systems, devices, mixers, results, streamers, or different digital sources. Its excessive channel separation minimizes crosstalk, preserving impartial indicators for multi-track recording, multi-sensor industrial measurements, or essential listening purposes.
Integration is easy because it options an I²C management interface, pin-selectable choices, and might function standalone. Working on a 3.3 V digital I/O provide and a 5 V analog provide, it achieves low energy consumption of 40–50 mW. Automated clock detection ensures easy power-up and power-down, simplifying system integration and permitting quick deployment.
Among the key options of the
- 128 dB SNR – clear, low-noise audio
- -99 dB THD+N – low distortion
- 105 dB PSRR at 1 kHz – much less energy noise
- 140 dB channel separation – minimal crosstalk
- Auto clock detection – easy begin/cease
- Standalone mode – straightforward {hardware} management
- Low energy – 40–50 mW
- QFN-32 package deal (5 × 5 mm) – small measurement
- Working temperature: -40 °C to +85 °C
The corporate claims that this resolution can substitute built-in DACs in playback methods or streamers to ship superior output to pre-amplifiers or exterior amplification. When paired with a pre-amplifier, it offers pure analog indicators with clear supply separation. It additionally matches into audio interfaces, offering correct, low-distortion output to studio displays or mixing consoles, preserving the complete 24-bit dynamic vary.
