The D2-IPS family (D2-24044) device is a high performance, integrated Class-D amplifier power stage. The four power stage outputs are configurable as four separate Half-Bridge outputs, as two Full-Bridge outputs, or combinations of Half-Bridge and Full-Bridge. Individual power stage overload monitoring, on-chip temperature monitoring, and common alert logic outputs provide protection to integrate with the final system's controller.

The D2-4P (D2-45057 and D2-45157) devices are complete System-on-Chip (SoC) Class-D digital audio amplifiers. These devices combine high performance integrated Power Stages, an optimized Audio Processor feature set, and a PWM controller to offer a complete, powerful, and very cost effective audio solution for high volume and cost-critical products. This 4th generation Digital Audio Processor (D2-4P) 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, which provides flexible loudspeaker drive solutions. Separate PWM outputs provide additional combinations to drive headphone outputs or line level stereo and subwoofer outputs.

The D2 Audio DSP D2-1 Family (D2-81412, D2-81431, D2-81433, and D2-81435) is a fully self-contained 4-channel digital amplifier controller System-On-Chip (SOC). The D2-1 Family enables rapid system design for manufacturers of home theater receivers, multi-room distributed audio systems, and powered speakers. The D2-1 Family contains a high-performance digital switching controller to play any input source on any output channel. A configurable audio signal processor provides equalization, volume control, tone control, and compression for each channel, as well as crossover and power limiting for powered speaker applications. The D2-1 Family includes 4-channels I2S/left-justified inputs (16-bit to 24-bit, 32kHz to 192kHz) and an optional S/PDIF receiver (16-bit to 24-bit). Boot options include: Self-boot from an external serial ROM, asynchronous SCI slave boot, and serial slave boot from a host microcontroller.

The D2-3(S) family (D2-92633-LR, D2-92634-LR, D2-92643-LR, D2-92683-QR, D2-92684-QR) of the D2-3 and D2-3S Digital Audio Processor devices are complete System on Chip (SoC) multi-channel digital sound processors and Class-D amplifier controllers. The integrated DSP provides efficient and configurable audio signal path processing including equalization, dynamic range compression, mixing, and filtering that is completely configurable using the D2 Audio Customization GUI v3 high level programming interface. The integrated PWM engine supports programmable and dynamic control of audio output, enabling a variety of multi-channel output configurations and output power capacity. Internal noise shaping, an embedded asynchronous sample rate converter, dynamic level-dependent timing, and high resolution operation support power stage audio performances with SNR >110dB and THD+N <0. 01%. The D2-3(S) devices are provided in two package and feature configurations which include the 128 Ld D2-3 family and the 72-pin D2-3S family. Both the D2-3 and D2-3S family provide identical performance and enable an extremely flexible platform for feature rich and cost-affordable quality audio solutions, which benefit from the addition of Class-D amplifiers and DSP audio processing. The 12 integrated digital PWM controllers can be used in a variety of multi-channel audio system configurations, supporting powered as well as line outputs. Fully protected amplifier control provides efficient and clean Class-D power output support.
