Audio codec

Audio codecs are responsible for converting between analogue and digital audio signals, and mainly include the following series:

High-fidelity (Hi-Fi) audio codecs: Support 24-bit/192kHz high-resolution audio, featuring extremely low signal-to-noise ratio (SNR) and total harmonic distortion (THD), suitable for high-end audio equipment, professional recording equipment, and car audio systems.

Low-power audio codecs: Specifically designed for portable devices such as smartphones, tablets, and wireless headphones. They maintain excellent audio quality while significantly reducing power consumption and extending battery life.

In-vehicle audio codecs: Specifically designed for automotive electronic environments, featuring a wide operating temperature range, high interference resistance, and multi-channel processing capabilities, capable of meeting the high requirements of automotive infotainment systems for audio processing.

Audio switches

Audio switches are critical components in audio signal paths, responsible for signal switching. They feature low distortion, high isolation, and small packaging. The main types include:

Analogue audio switches: Used for switching analogue audio signals, they have ultra-low on-resistance (RON) and extremely high off-isolation, effectively maintaining audio signal integrity. They are widely used in mixers, audio interfaces, and consumer electronics devices.

Digital audio switches: Support signal routing for digital audio interfaces such as I2S, PCM, and TDM. These switches are widely used in professional audio equipment and communication devices, enabling flexible configuration of multi-channel digital audio.

Audio switches with volume control functionality: Integrate switching and digital volume control functionality, simplifying system design and offering particular value in space-constrained applications.

USB audio solutions

With the widespread adoption of the USB Audio Class (UAC) standard, USB audio devices have become mainstream in the consumer electronics market, including:

USB audio codecs: Single-chip solutions that integrate USB interface controllers and audio codecs, simplifying the design of USB audio devices and widely used in USB headphones, USB microphones, and USB sound cards.

USB audio bridge chips: These chips convert traditional audio interfaces (such as I2S and PCM) to USB, commonly used to upgrade existing audio designs to USB-compatible devices.

High-performance USB audio processors: Designed for professional audio applications, these processors support high-resolution audio and multi-channel processing, with stable demand in recording studio equipment and professional audio systems.

Wireless audio chips

The wireless audio market has grown rapidly in recent years, with related products mainly including:

Bluetooth audio solutions: Support the latest Bluetooth 5.x standard and high-quality audio codecs (such as aptX, LDAC, etc.), widely used in wireless headphones, Bluetooth speakers, and in-car Bluetooth systems.

Proprietary wireless audio chips: Wireless audio transmission solutions using 2.4GHz or 5.8GHz proprietary protocols, featuring low latency and high reliability, suitable for professional wireless microphones and monitoring systems.

Wireless audio processors: SoC solutions integrating wireless interfaces and audio processing functions, simplifying the system design of wireless audio products.
