Package
Description
STA335ML is a single die embedding digital audio
processing and high-efficiency power
amplification, capable of operating without the aid
of an external microcontroller.
The STA335ML 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 STA335ML combines a unique 24-bit DDX
digital class-D ternary modulator together with an
extremely low R
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 (cradle, digital speakers, audio
terminals) where no microcontroller is needed.
The serial audio data interface accepts the
universally used I
as oversampling clock, gain, I
using a minimal number of selection pins.
STA335ML 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.
