Processes PCM audio data streams up to 32-bit depth.
Based on common implementation data found at retailers like Concept Kart and Amazon , here are the core specs: Supports up to 32-bit / 384kHz .
This output capability is sufficient for most portable headphones and IEMs. While the CX31993 is not designed to drive extremely power-hungry planar magnetic headphones to their full potential, it provides ample power for the vast majority of consumer and enthusiast-grade headphones. cx31993 datasheet
A: Many product descriptions claim DSD support, but this is likely implemented through DoP (DSD over PCM) , a software-based conversion method, rather than native hardware decoding. For users who primarily listen to PCM-based high-resolution audio (FLAC, ALAC, WAV), this is not a practical limitation.
Conexant CX31993 (often branded as CX-Pro) is a highly efficient, high-performance USB-C Digital-to-Analog Converter (DAC) and integrated amplifier chip. It has gained widespread popularity in the "dongle DAC" market due to its ability to deliver high-resolution audio—up to 32-bit/384kHz —in a compact, low-power form factor.

Designing hardware with the CX31993 requires careful attention to trace routing, grounding strategies, and decoupling networks to maintain the chip's native 124 dB SNR.

For hardware engineers designing a device, choosing a codec is a balancing act between price, board real estate, and audio fidelity. The CX31993 is often selected for its .
