The datasheet for the CX31993 reveals a chip designed for audiophile-grade transparency at a budget price point. Key performance metrics include: Specification Sampling Rate 32-bit / 384kHz (PCM) Signal-to-Noise Ratio (SNR) Dynamic Range (DNR) 0.0003% (-95dB) Output Power (Thrust) 65mW per channel @ 32Ω DSD Support DSD 64/128 (via PCM conversion)
The CX31993 integrates a digital-to-analog converter (DAC), an analog-to-digital converter (ADC), a high-efficiency headphone amplifier, and a USB 2.0 full-speed/high-speed controller onto a single silicon die. This high level of integration eliminates the need for an external microcontroller or a separate audio bridge chip, minimizing the overall printed circuit board (PCB) footprint and reducing bill-of-materials (BOM) costs. 2.
