STA3398 Datasheet - STMicroelectronics

STA3398 - > Correct PartNumber STA339B

STA3398W - > Correct PartNumber STA339BW

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, a 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.
