Cx31993 Datasheet [exclusive] -

The internal design of the CX31993 is built around efficiency and high-fidelity routing:

For engineers and product designers considering the CX31993 for their projects, the following implementation notes are essential:

When paired with the MAX97220, typical performance specifications improve: cx31993 datasheet

Regulated voltage output to power electret condenser microphones.

A: Conexant (now part of Synaptics) has not publicly released the full technical datasheet for the CX31993. Some sources indicate that official technical documentation for this chip may have been discontinued. This article synthesizes information from product implementations, technical analyses, and independent measurements to provide the most complete technical picture currently available. The internal design of the CX31993 is built

A: No. The chip is powered entirely through the USB-C connection and does not require any external power source. This is a key advantage for portable applications.

Driven by the internal Class-G headphone amplifier. This is a key advantage for portable applications

The CX31993 is a highly integrated, low-power USB Type-C digital audio codec designed by Conexant (now part of Synaptics). It has become a dominant component in the portable audio market, specifically powering high-resolution USB-C to 3.5mm dongles, external DACs (Digital-to-Analog Converters), and inline headphone amplifiers.
