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 RdsONstereo 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.Key Features
