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.
