Datasheet — Cx31993

Digital-to-Analog Converter (DAC) chip—gained "dark horse" status because it was powerful, cheap, and surprisingly difficult to find technical documentation for. 1. The "Hidden Gem" Discovery The CX31993 chip first rose to fame through the

Beyond pure music playback, the CX31993 supports . This feature enables headsets with inline microphones to be used for voice calls, gaming communication, and voice recording, expanding the chip's utility beyond dedicated music listening. cx31993 datasheet

The CX31993 is designed for high-fidelity audio playback. Its decoding capability ensures it can handle high-resolution audio files without downsampling, preserving all the original detail. The key to its "Hi-Fi" designation lies in its >128dB SNR , which means the audio signal is significantly louder than the background noise, resulting in an exceptionally clean and "black" background. This is further supported by a THD+N of less than 0.0003% , indicating extremely low distortion. While some community members note that the 1Vrms output may have higher distortion compared to certain alternatives, its overall noise floor remains very low. This feature enables headsets with inline microphones to

The (often associated with the Conexant CX-Pro series) has emerged as a dominant force in the budget-friendly, high-fidelity portable audio market . As mobile manufacturers continue to remove 3.5mm headphone jacks, demand for high-quality USB-C DAC (Digital-to-Analog Converter) and Amp dongles has surged. The key to its "Hi-Fi" designation lies in

Supports up to 32-bit / 384kHz , putting it well into the "Hi-Res" territory.

Integrated Acoustic Echo Cancellation (AEC) support and digital noise suppression filters via firmware configuration. Headphone Amplifier Output Output Power: Up to 65mW per channel into 32 Ωcap omega
