Audio decoder module for MP3 and WAV playback that delivers accurate PCM output and wide power compatibility. Key benefits Wide power range: Operates from DC 6 ~ 35 V, allowing direct use with 12 V car systems, 24 V industrial supplies, battery packs and other DC sources without extra converters. High-fidelity output: 24-bit output with a supported dynamic range of 90 dB and a signal-to-noise ratio of 85 dB for clear, low-noise playback. Broad sample-rate support: Decodes audio at 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48 kHz to match common media and production standards. Format compatibility: Native MP3 and WAV decoding for straightforward playback of the most widely used audio files. What this solves Eliminates the need for separate DAC modules when you require decoded 24-bit PCM output. Reduces power-supply complexity by accepting an ultrawide DC input range. Ensures accurate playback across standard sample rates and common file formats, avoiding resampling artifacts or format conversion steps. Performance and compatibility Supported sample rates (kHz): 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48 Power supply: DC 6 ~ 35 V (ultrawide operating voltage) Audio output: 24-bit output, dynamic range supported 90 dB, signal-to-noise ratio supported 85 dB Decoding formats: MP3, WAV Practical use scenarios In-vehicle audio systems: Run directly from a car battery (12 V) for MP3/WAV playback with minimal power conditioning. Industrial or commercial installations: Drive announcements or background music from 24 V systems without additional power conversion. Embedded and DIY audio projects: Provide high-resolution decoded audio (24-bit PCM) for custom players, kiosks, or portable devices that require multiple sample-rate support. Notes for integrators Use the module where decoded 24-bit output and wide DC input range simplify system design. Confirm downstream equipment accepts the module’s 24-bit PCM output and supported sample rates.
