Description
The STA380WS is an integrated circuit
comprising digital audio processing, digital
amplifier control and FFX power output stage to
create a high-power, single-chip FFX solution for
all-digital amplification with high quality and high
efficiency.
The STA380WS power section can provide up to
20 W + 20 W BTL output power.
Also provided in the STA380WS are new
advanced AM radio interference reduction
modes. The serial audio data input interface
accepts all possible formats, including the popular
I2S format.
The STA380WS is part of the 2-channel high-
efficiency digital audio system family that provides
full digital audio streaming to the speaker offering
cost effectiveness, low power dissipation and
sound enrichment.
