1 / 14 page  May 2008 Rev 2 1/14 14 STA333ML Sound Terminal™ 2-channel microless high-efficiency digital audio system Features ! Wide supply voltage range (4.5 - 18 V) ! 2 x 20 W into 8 Ω at Vcc = 18 V ! 3 power output configurations; 2 channels of ternary PWM ! PowerSSO-36 exposed pad package ! 2 channels of 24-Bit DDX® ! 100-dB SNR and dynamic range ! 32 kHz to 48 kHz input sample rates ! Soft volume update ! Automatic zero-detect mute ! Automatic invalid input detect mute ! 2-channel I2S input data interface ! Selectable clock input ratio (256 or 364 x fs) ! Max power correction for lower full power ! 96 kHz internal processing sample rate, 24-bit precision ! Thermal overload and short-circuit protection embedded Applications ! LCD ! DVD ! Cradle ! Digital speaker ! Wireless speaker cradle Description STA333ML is a single die embedding digital audio processing and high efficiency DDX® power amplification, capable of operating without the aid of an external micro controller. The STA333ML is part of the Sound Terminal™ family that provides full digital audio streaming to the speaker offering cost effectiveness, low energy dissipation and sound enrichment. The STA333ML combines a unique 24-bit DDX® digital class-D ternary modulator together with an extremely low RDSON stereo power DMOS stage. It is capable of a total output power of 2 x 20 W with outstanding performance in terms of efficiency (>90 %), THD, SNR and EMI. The microless feature allows the use in low-cost applications (cradle, digital speakers, audio terminals) where no micro controller is needed. The serial audio data interface accepts the universally used I2S format. Basic features (like oversampling clock, gain and I2S format) can be set using a minimal number of selection pins. The STA333ML is self-protected against thermal overload, overcurrent, short circuit and overvoltage conditions. The fault condition is also exported to an external pin (INT_LINE) for specific requirements. PowerSSO-36 slug down Table 1.
