The STA323W is a single-chip audio system comprising digital audio processing, digital amplifier control and a DDX®power-output stage. The STA323W uses all-digital amplification to provide high-power, high-quality and high-efficiency.


The STA323W power section consists of four independent half-bridges. These can be configured, by digital control, to operate in the following modes.


Two channels, provided by two half-bridges, and a single full-bridge giving up to 2 x 10 W + 1 x 20 W of power output.


Two channels, provided by two full-bridges, giving up to 2 x 20 W of power.


A single, parallel, full-bridge channel capable of high-current operation and giving 1 x 40W output.


The STA323W also provides a full set of digital processing features. This includes up to four programmable 28-bit biquads (EQ) per channel, and bass and treble tone control. AutoModes™ enable a time-to-market advantage by substantially reducing the amount of software development needed for specific functions. These includes auto volume loudness, preset volume curves and preset EQ settings. New advanced AM radio-interference reduction modes are also provided.


The serial audio data input interface accepts all existing formats, including the I²S.


Three channels of DDX®processing are provided. This high-quality conversion from PCM audio to DDX patented 3-state PWM switching provides over 100 dB of SNR and dynamic range.
