Digital Audio System 36-Pin PowerSSO EP T/R

The STA333W is an integrated circuit comprising digital audio processing, digital amplifier control and DDX power output stage to create a high-power, 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.
