Description
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
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.
