STA32613TR

STA32613TR is a 2.1-channel high-efficiency digital audio system. This comprises digital audio processing, digital amplifier control and DDX® power output stage to create a high-power single-chip DDX® solution for high-quality, high-efficiency, all-digital amplification. This 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 to give up to 2 x 40W plus 1 x 80W of power output. Two channels can be provided by two full-bridges to give up to 2 x 80W of power. The IC can also be configured as a single parallel full-bridge capable of high-current operation and 1 x 160W output. Also provided in the STA326 is a full assortment of digital processing features. This includes up to four programmable 28-bit biquads (EQ) per channel and bass/treble tone control.
