STA333ML Datasheet | STMicroelectronics

Description Power SSO-36 with exposed pad down (EPD) Features - Wide supply voltage range (4.5 - 20 V) - 2 x 20 W into 8 at VCC = 18 V - Power SSO-36 exposed pad package - 2 channels of 24-bit DDX® - 100-d B SNR and dynamic range - Selectable 32 k Hz to 48 k Hz input sample rates - Automatic zero-detect mute - Automatic invalid input detect mute - 2-channel I2S input data interface - Selectable clock input ratio (256 or 364 - fs) - Max power correction for lower full power - 96 k Hz internal processing sample rate, 24-bit precision - Embedded thermal overload and short-circuit protection - Filterless configuration option The STA333ML is a single die embedding digital audio processing and high-efficiency power amplification, capable of operating without the aid of an external microcontroller. The STA333ML is part of the Sound Terminal® family that provides full digital audio streaming to the speakers and offers cost effectiveness, low power dissipation and sound enrichment. The STA333ML bines a unique 24-bit DDX® digital class-D ternary modulator together with an extremely low Rds ON stereo power DMOS stage. The latter 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 its use in low-cost applications (cradles, digital speakers, audio terminals) where no microcontroller is needed. The serial audio data interface accepts the universally used I2S format. Basic features , such as the 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 signalled on an external pin (INT_LINE) for specific requirements. Applications - LCDs - DVDs - Cradles - Digital speakers Order code STA333ML13TR Table 1.
