Cx31993 Datasheet Page

is a highly efficient, single-chip USB Type-C digital-to-analog converter (DAC) and headphone amplifier . This system-on-chip (SoC) has become a primary choice for audiophile dongles, ultra-portable amplifiers, and custom hardware integration. The device natively delivers combined with exceptionally low power draw.

The chip utilizes a multi-bit Delta-Sigma modulator. This allows it to handle high-resolution files (PCM) with minimal quantization noise. The 32-bit depth ensures that even the quietest passages in a recording are reproduced with precision. Adaptive Power Management cx31993 datasheet

The datasheet figures reveal a limitation: the CX31993 is optimized for and low-impedance headphones. With a max output of 1.2Vrms, it struggles to drive high-impedance studio headphones (e.g., Sennheiser HD600 series at 300Ω). On a 300Ω load, the power output drops to roughly 0.5mW, resulting in low volume. The chip utilizes a multi-bit Delta-Sigma modulator
