The STA326 can be configured via digital control to operate in several output modes providing up to 2.1 channels of power output to speakers. This device is capable to deliver up to 2x30W + 1x60W in 2.1 mode or 2x60W in stereo mode. The IC can also be configured as a single paralelled full-bridge capable of high-current oper- ation and 1x120W output. Also provided in the STA326 are a full assortment of digital processing features. This includes up to 4 programmable 28-bit biquads (EQ) per channel, and bass/treble tone control. Automodes™ enable a time-to-market advantage by substantially re- ducing the amount of software development need- ed for certain functions. This includes Auto 2.1 HIGH EFFICIENCY DIGITAL AUDIO SYSTEM Rev. 2 Figure 1. Package Table 1. Order Codes Part Number Package STA326 PowerSO36 (Slug up) STA32613TR Tape & Reel PowerSO36 (Slug up) |
