Upgraded DAC chip, using the higher-end PCM5122 chip from BB (acquired by TI), with I2S interface and the ability to adjust volume and audio parameters via the I2C interface. Supports 16 to 32-bit audio data formats, with ideal distortion and dynamic performance. It supports a high sample rate of up to 384kHz, a dynamic range of 112dB, and distortion of -93dB. Features soft rise or fall slopes with no click noise and analog noise suppression for a 120dB SNR with excellent noise suppression.\u003c\/p\u003e \u003c\/li\u003e \u003cli\u003e \u003cp\u003e2. The PCM5122 also integrates a negative charge pump, eliminating the need for DC coupling capacitors at the output. It provides a 2.1Vrms ground-centered output with excellent out-of-band noise suppression. With a load as low as 1kΩ, the PCM510xA can drive multiple parallel products (i.e., multiple amplifiers used simultaneously).\u003c\/p\u003e \u003c\/li\u003e \u003cli\u003e \u003cp\u003e3.

Isolated power design ensures that the Raspberry Pi power supply is electrically separated from the DAC section, and mutual interference is prevented through magnetic beads and shared ground, eliminating current noise.\u003c\/p\u003e \u003c\/li\u003e \u003cli\u003e \u003cp\u003e5. No soldering required; simply plug the expansion board in to use. It uses an I2S interface for direct digital-to-analog decoding, rather than the USB interface DAC method.\u003c\/p\u003e \u003c\/li\u003e \u003cli\u003e \u003cp\u003e6. Provides dual-color LED status display: red indicates DAC power (lit when power is normal), green indicates DAC working status (lit during decoding, off when idle or not working), offering better insight into the DAC's operational status.\u003c\/p\u003e \u003c\/li\u003e \u003cli\u003e \u003cp\u003e7. Perfectly compatible with Raspberry Pi official PI HAT size, PCB board uses high-end gold-plated technology, with curved routing (high-end HIFI DACs use curved routing) to better ensure signal impedance continuity and reduce signal reflection and refraction.\u003c\/p\u003e \u003c\/li\u003e \u003cli\u003e \u003cp\u003e8. High-quality sound relies on genuine, premium components.
