Cx31993 Datasheet Jun 2026

is a solution aimed at improving the sound quality of smartphones, laptops, and tablets that lack a traditional headphone jack. It functions as an "all-in-one" single-chip solution designed to replace the substandard, noisy onboard audio chips found in many consumer devices. Key Characteristics:

For consumers, devices powered by the CX31993 provide an affordable pathway to audibly transparent audio reproduction. Whether used as a simple USB-C to 3.5mm adapter or integrated into a more sophisticated portable DAC/amp, the CX31993 consistently delivers clean, accurate, and detailed sound that fully reveals the nuances of high-resolution recordings.

Mono/Stereo capablities with integrated low-noise microphone bias (Mic-Bias) Sampling Rate Support: Up to 24-bit / 96 kHz cx31993 datasheet

: Measurement data shows excellent linearity across the audible frequency range (20Hz–20kHz).

Approximately 0.0003% (-95dB), indicating high transparency. is a solution aimed at improving the sound

The versatility of the CX31993 makes it suitable for a wide array of audio applications.

The CX31993 can be directly connected to an external headphone amplifier such as the or SGM8262 to increase output power. The integration typically involves:

Over 120dB , allowing for great separation between the quietest and loudest parts of your music.

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

Based on the ⁠Conexant CX-Pro CX31993 review , this chip offers the best "bang for the buck."
