Intelligent Digital Amplifier and Sound Processor
D2-926xx
Features
The D2-926xx family of the DAE-3™ and DAE-3HT™ Digital
Audio Engine™ devices are complete System-on Chip (SoC)
multi-channel digital sound processors and Class-D amplifier
controllers.
• Advanced DAE-3™ Digital Audio Engine™ IC Family
- DAE-3™ Pin Compatible and Function/Feature
Compatible with the D2Audio™ DAE-6™ Device Family
- DAE-3HT™ - Identical DAE-3 performance, in
72-QFN package
The integrated DSP provides efficient and configurable audio
signal path processing including equalization, dynamic range
compression, mixing, and filtering that is completely
• Integrated DSP Digital Sound Processing
- Customizable audio path sound processing
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%.
- Fully configurable and routable audio signal paths and
hardware function assignment
- Fully Supported with Audio Canvas™ III Design Tool
• Flexible Audio Input and Output Configurations
- 12 Independent PWM Engine Channels
2
- 4 Independent Asynchronous I S Digital Inputs
- Integrated high-performance stereo ADC (DAE-3 only)
The D2-926xx devices are provided in two package and feature
configurations which include the 128-pin DAE-3, and the72-pin
DAE-3HT. Both the DAE-3 and DAE-3HT 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.
- S/PDIF™ Digital Audio Inputs supporting
Linear IEC-61958 PCM or Compressed IEC-61937 Audio
- S/PDIF Digital Audio PCM Output
• Embedded 8-Channel Sample Rate Converter
• Real-Time Amplifier Control and Monitoring
- Supports Bridged, Half-Bridged, and Bridge-Tied Load (BTL)
Topologies, Using Discrete or Integrated Power Stages
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.
