Intelligent Digital Amplifier PWM Controller and
Audio Processor
D2-45057, D2-45157
The D2-45057 and D2-45157 devices are complete
System-on-Chip (SoC) Class-D digital audio amplifiers.
Combining high performance integrated Power Stages
along with an optimized Audio Processor feature set and
PWM Controller, these devices offer a complete,
powerful, and very cost effective audio solution for high
volume and cost-critical products.
This 4th generation Digital Audio Engine (DAE-4P)
device combines extensive integrated Digital Signal
Processor (DSP) audio processing with amplifier control,
for a complete audio solution. Its ease of integration into
the existing system processor provides complete support
for all system product and amplifier functions.
The four configurable Power Stages operate as four
separate Half-Bridge outputs, as two Full-Bridge outputs,
or in combinations of Half-Bridge plus Full-Bridge,
providing flexible loudspeaker drive solutions. Separate
PWM outputs provide additional combinations to drive
headphone, or line level stereo and subwoofer outputs.
