Description

The STA333IS is an integrated circuit comprising

digital audio processing, digital amplifier control

and an FFX™ power output stage to create a

high-power, single-chip FFX solution for all-digital

amplification with high quality and high efficiency.

The STA333IS power section consists of four

independent half-bridge stages. Two channels

can be provided by two full bridges, delivering up

to 10 W + 10 W of power.

Also featured in the STA333IS are new advanced

modes for reducing AM radio interference. The

serial audio data input interface accepts all

possible formats, including the popular I2S format.

Two channels of FFX™ processing are provided.

The STA333IS is part of the Sound Terminal®

family that provides full digital audio streaming to

the speaker, offering cost effectiveness, low-

power dissipation and sound enrichment.
