Product overview

Description

The STA333IS is an integrated circuit comprising digital audio processing, digital amplifier control and an FFXpower 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 FFXprocessing 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.
