Audio decoder and playback module designed for reliable, high-fidelity output and wide power compatibility. Key features and specifications 24-bit output resolution for accurate digital-to-analog conversion. Dynamic range: 90 dB — preserves detail and headroom in audio playback. Signal-to-noise ratio (SNR): 85 dB — low background noise for clearer sound. Ultra-wide operating voltage: DC 6 ~ 35 V — works with a broad range of power sources. Supported decoding formats: MP3, WAV. Supported sample rates (kHz): 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48. Customer benefits — why this solves real problems Cleaner, more detailed audio: 24-bit output combined with a 90 dB dynamic range and 85 dB SNR reduces distortion and noise, which improves clarity for music, voice prompts, and recorded audio. Flexible power integration: The DC 6–35 V range allows use with automotive electrical systems, common battery voltages, or industrial supplies without additional converters. Broad format and sample-rate compatibility: Native MP3 and WAV decoding plus support for common sample rates means easy integration with existing audio files and systems without extra file conversion. Reliable performance in constrained environments: The specified electrical and audio performance helps maintain consistent playback quality across different deployments. Practical applications and use scenarios Vehicle audio and infotainment: Integrate into car or marine audio systems that operate on varied voltages to add MP3/WAV playback with good fidelity and low noise. Portable and DIY speaker projects: Use in battery-powered or multi-voltage designs to deliver higher-resolution audio and reduce audible background hiss. Embedded systems and industrial signage: Provide clear audio prompts or background music in kiosks, vending machines, or control panels where power supply may vary. What to consider when integrating Match file formats and sample rates to the supported list to ensure optimal decoding without resampling. Verify your system’s supply voltage falls within DC 6–35 V to avoid the need for external regulation. Use appropriate output stages and filtering as required by your final speaker or amplifier design to capitalize on the 24-bit output and noise performance. This module offers a balance of audio performance and power flexibility for applications that require reliable MP3/WAV playback across varied voltage environments.
