STA333ML13TR

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_dsONstereo 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.
