D2-45057 Product Details

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.
