Description
The STA339BWS is an integrated solution of digital audio processing, digital amplifier
controls and power output stage to create a high-power single-chip FFX digital amplifier with
high-quality and high-efficiency. Three channels of FFX processing are provided. The FFX
processor implements the ternary, binary and binary differential processing capabilities of
the full FFX processor.
The STA339BWS is part of the Sound Terminal™ family that provides full digital audio
streaming to the speakers and offers cost effectiveness, low power dissipation and sound
enrichment.
The power section consists of four independent half-bridges. These can be configured via
digital control to operate in different modes.

Also provided in the STA339BWS are a full assortment of digital processing features. This
includes up to 8 programmable biquads (EQ) per channel. Available presets enable a time-
to-market advantage by substantially reducing the amount of software development needed
for functions such as audio preset volume loudness, preset volume curves and preset EQ
settings. There are also new advanced AM radio interference reduction modes. Dual-band
DRC dynamically equalizes the system to provide linear frequency speaker response
2.1 channels can be provided by two half-bridges and a single full-bridge, supplying up
to 2 x 9 W + 1 x 20 W of output power.
Two channels can be provided by two full-bridges, supplying up to 2 x 20 W of output
power.
The IC can also be configured as 2.1 channels with 2 x 20 W supplied by the device
plus a drive for an external FFX power amplifier, such as STA533WF or STA515W.
