STA339BW SSO-36

2.1-channel high-efficiency digital audio system

The STA339BW is an integrated solution of digital audio processing, digital amplifier control, and FFX-power output stage, thereby creating a high-power single-chip FFX^®solution comprising high-quality, high-efficiency, all digital amplification.

STA339BW is based on FFX (fully flexible amplification) processor, an STMicroelectronics proprietary technology. FFX is the evolution and the enlargement of the ST ternary technology: the new processor can be configured to work in ternary, binary, binary differential and phase shift PWM modulation schemes.

STA339BW contains the ternary, binary and binary differential implementations, a subset of the full capability of the FFX processor.

The STA339BW is part of the Sound Terminal^®family that provides full digital audio streaming to the speaker, offering cost

effectiveness, low power dissipation and sound enrichment.
