STA333W Sound Terminal Digital Audio Subsystems by STMicroelectronics

2-channel high-efficiency digital audio system


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 I 2 S 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.
