DAE3
The DAE-3™ Digital Audio Engine™ devices are complete System-on Chip (SoC) multi-channel digital sound processors and Class-D amplifier controllers. The DAE-3, provided in function-specific part numbers for accommodating optional compressed audio format decoding, is a member of both the digital sound processor and decoding sound processor families.
The integrated DSP provides efficient and configurable audio signal path processing including equalization, dynamic range compression, mixing, and filtering that is completely configurable via the Audio Canvas™ III 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 supports power stage audio performances with SNR >110dB and THD+N < 0.01%.
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.
The DAE-3 is fully supported with our Audio Canvas III sound design tool, enabling custom-made signal flow and hardware function configuration. Unique features of the DAE-3 include:
- Complete audio input and output channel assignment and configuration
- Programmable I2S digital audio format selections
- Integrated and independent Asynchronous Sample Rate Converters (ASRC) for up to 8 audio input channels
- Designer-configurable hardware I/O features and interface assignments
- Real-time per-channel PWM timing and control and programmable PWM switching frequencies
- Intelligent over-current and short-circuit protection
- Integrated temperature monitoring and thermal protection
- Selectable clock outputs supporting synchronizing of amplifier operation and audio interfaces
- Support of SRS TruSurround HD4™, SRS WOW HD4™, SRS TruVolume™ as well as D2Audio SoundSuite™
When ordered as its decoding sound processor part number, D2-92634, the DAE-3 additionally supports:
- Decoding of industry standard Dolby Digital®, DTS®, and AAC® compressed audio formats
- Dolby ProLogic II®, Dolby ProLogic IIx®, and Dolby Virtual Speaker® virtualization and enhancements
