Description

The STA333W is an integrated circuit comprising

digital audio processing, digital amplifier control

and DDX? power output stage to create a highpower, single-chip DDX? solution for all-digital

amplification with high quality and high efficiency.

The STA333W power section consists of four

independent half-bridges stages. These can be

configured via digital control to operate in different

modes. 2 channels can be provided by two full

bridges, providing up to 20 W + 20 W of power.

Also provided in the STA333W are new advanced

AM radio interference reduction modes. The serial

audio data input interface accepts all possible

formats, including the popular I2S format. Three

channels of DDX? processing are provided.

The STA333W 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.
