Description
The STA380BW is an integrated solution embedding digital audio processing, digital
amplification and FFXTM power output stage. It is part of the Sound Terminal? family and
provides full digital audio streaming from the source to the speaker, offering cost
effectiveness, low power dissipation and sound enrichment.
The STA380BW input section consists of a flexible digital input serial audio interface feeding
the digital processing unit. The serial audio data input interface supports many formats,
including the popular IIS format.
The STA380BW is based on an FFXTM (Fully Flexible Amplification) processor, proprietary
technology from STMicroelectronics. FFXTM is the evolution of the ST ternary technology:
the advanced processor is available for ternary, binary, binary differential and phase shift
PWM modulation. The STA380BW embeds the ternary, binary and binary differential
implementations, a subset of the full capability of the FFXTM processor.
The STA380BW power section consists of four independent half-bridges. These can be
configured via digital control to operate in different modes. A 2.1-channel setup can be
implemented with two half-bridges (L/R) together with a single full-bridge (subwoofer).
Alternatively, the 2.0-channel setup can be done with two full-bridges. When using this
configuration, an external amplifier for the SW channel can also be driven through the PWM
output. The STA380BW is able to deliver 2 x 20 W (ternary) into an 8 ? load at 18 V or
2 x 9 W (binary) into a 4 ? load, plus 1 x 20 W (ternary) into an 8 ? load at 18 V.
The STA380BW digital processing unit includes up to 12 programmable biquads (EQs),
allowing perfect sound equalization and offering advanced noise-shaping techniques.
Moreover, the coefficient range ensures a great variety of filter shapes (low/high-pass,
low/high shelf, peak, notch, band-pass). The equalization engine is fully compatible with the
ST speaker compensation technology embedded into the APWorkbench suite. A state-ofthe-
art multi-band DRC, STCompressorTM equalizes the system to provide active speaker
protection with full audio quality preservation against sudden sound peaks. Moreover,
STSpeakerSafeTM technology offers reliable speaker protection under any condition. The
master clock can be from stable BICKI (64xfs, 50 duty cycle) or external XTI. Obsolete
