A breakthrough in digital audio systems, Sound Terminal™ digital audio ICs enable space-constrained audio applications, such as flat-screen TVs and MP3 docking stations, to deliver high-quality, room-filling sound. Using techniques such as Full Flexible Amplification (FFX), and integrating advanced DSP processing features such as multi-band DRC, this family enables a fully digital stream from sound source to loudspeaker.
In application, this produces improved audio performance, reduced cost, and smaller size, making it possible for leading home-entertainment equipment manufacturers to deliver best-in-class audio experiences for consumers.
Key benefits are:
- Analog and digital interfaces, eliminating the need for an external mux or analog-to-digital converter
- Dynamic range compressor for sound enhancement and speaker protection
- Space-saving packages such as QFN and BGA
- Fully-integrated graphical development environment (Audio Processor Workbench) for easy device configuration
STA333IS: digital audio system-on-chip
The STA333IS is the most power dense single-chip digital audio system available today and extends ST’s SoundTerminal™ family, combining advanced process and chip-scale package technologies with digital audio IP such as ST’s proprietary FFX full flexible amplification.
The STA333IS is unique in the marketplace, since only ST has the technologies and audio IP (Intellectual Property) to combine advanced signal processing and power circuitry on a single chip. With its wide operating voltage range, from 4.5V to 18V, it is ideal for battery-operated equipment as well as space-constrained products such as LCD or LED televisions, docking stations and digital wireless speaker systems.
