STA333ML

STA333ML 2-channel microless high-efficiency digital audio system Sound Terminal ® Datasheet - production data  Wireless speaker cradles Description PowerSSO-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  PowerSSO-36 exposed pad package  2 channels of 24-bit DDX®  100-dB SNR and dynamic range  Selectable 32 kHz to 48 kHz 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 kHz 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 combines a unique 24-bit DDX® digital class-D ternary modulator together with an extremely low RdsON 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 te...
