Place 0.1µF and 4.7µF ceramic capacitors as close as physically possible to the VBUS and internal LDO output pins.
The chip supports in-line controls (volume/play/pause) and microphone input for calls.
A key simplification for hardware designers is the chip's . This "no-crystal" design eliminates the need for an external crystal oscillator, reducing the bill of materials (BOM) and simplifying PCB layout, which allows for highly compact product designs. For engineers looking to adapt the CX31993 for advanced sensor or audio front-end applications, note that there is also an "AFE" (Analog Front-End) version of the chip for measurement and sensing. This variant supports advanced features like programmable gain amplifiers (PGA), multiplexers, and sigma-delta ADCs, configurable via an I2C interface . cx31993 datasheet
The reveals a highly capable DAC designed for modern, portable high-res audio. Its combination of high SNR, low THD, and strong driving power in a tiny USB-C package makes it an excellent choice for users looking to upgrade their mobile listening experience without spending a fortune.
The is a compact, integrated Hi-Res Lossless Music DAC and headphone amplifier designed specifically for USB-C audio applications. It is manufactured by Conexant, aiming to provide high-quality audio conversion, allowing users to experience superior sound quality over standard USB-C to 3.5mm passive adapters. Place 0
While an official "public" datasheet for the is notoriously difficult to find due to its legacy status and Synaptics' acquisition of Conexant in 2017, the following technical specifications have been compiled from reliable product listings and community measurements. Core Technical Specifications
The versatility of the CX31993 makes it suitable for a wide array of audio applications. This "no-crystal" design eliminates the need for an
: It supports high-resolution PCM files, allowing you to listen to "Master" quality tracks on streaming services like Tidal or Apple Music without downsampling. Low Power Consumption : Unlike some desktop-grade portable DACs, the CX31993 Go to product viewer dialog for this item.
Elias looked around. The security camera in the corner was a dummy unit, its lens long since shattered. He tapped the 'Open' command.
