The SoC is also able to compensate non-ideal speaker characteristics. Enhancements introduced in this generation include optimized low-frequency response for outstanding bass performance. In addition, integrated protection features safeguard the system against a wide range of fault conditions. Run-time automatic diagnostic circuitry helps prevent failures and boosts the overall reliability of the application.

The IC’s power stage uses ST’s FFX technology to stream full digital audio to the speakers. This maximizes flexibility for configurable products by providing four selectable run-time output configurations supporting a choice of operating modes including 2.0, 2.1 or 1.0 channel, or 2.0-channel with a PWM output for an external subwoofer. The IC comes in a PowerSSO 36-pin slug-down package supporting convenient low-cost system design
