STA333ML Sound Terminal Digital Audio Subsystems by STMicroelectronics

Sound Terminal 2-channel microless high-efficiency digital audio system


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 R dsON 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 I 2 S format. Basic features, such as the oversampling clock, gain, and I 2 S 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.
