The STA328 is an integrated solution of digital audio processing, digital amplifier control, and DDXPower Output Stage, thereby creating a high-power single-chip DDX solution comprising of highquality, high-efficiency, all digital amplification. The STA328 power section consists of four independent half-bridges. These can be configured via digital control to operate in different modes. 2.1 channels can be provided by two half-bridges and a single full-bridge, providing up to 2x40W + 1x80W of power output. 2 Channels can be provided by two full-bridges, providing up to 2x80W of power. The IC can also be configured as a single paralelled full-bridge capable of high-current operation and 1x160W output. Also provided in the STA328 are a full assortment of digital processing features. This includes up to 4 programmable 28-bit biquads (EQ) per channel, Rev. 3
