Description FFX
STA335W
The STA335W 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.
STA335W is based on FFX (Full Flexible Amplification) processor.
The STA335W is part of the Sound TerminalTM family that provides full digital audio
streaming to the speaker, offering cost effectiveness, low power dissipation and sound
enrichment.
The STA335W power section consists of two full-bridges. The two channels can provide up
to 2 x 20 W of power.
The serial audio data input interface accepts all possible formats, including the popular I2S
format. Two channels of FFX processing are provided. This high-quality conversion from
PCM audio to FFX PWM switching waveform provides over 100 dB SNR and dynamic
range.
