CJMCU-5102 PCM5102 24-bit I2S Digital Audio DAC Decoder Module – 3.5mm Stereo Output
The CJMCU-5102 PCM5102 Digital Audio DAC Decoder Module is a compact, high-performance audio decoding board based on the Texas Instruments PCM5102 stereo DAC. It converts digital I2S audio signals into high-quality analog stereo audio through a 3.5mm line-out jack, making it ideal for DIY audio systems, Raspberry Pi projects, ESP32 audio applications, digital amplifiers, and embedded multimedia devices.
Supporting 16-bit, 24-bit, and 32-bit PCM audio with sampling rates up to 384kHz, the module delivers crystal-clear sound with excellent dynamic range and low distortion. The PCM5102 features an integrated PLL, allowing it to operate without an external master clock (MCLK) in many applications, simplifying hardware design. Its low-noise architecture and pop-free output ensure clean audio playback suitable for Hi-Fi and multimedia systems.
