D2-7xx83
Introduction
The DAE-6 family of ICs provide the core functionality, amplifier
control, and complete audio signal processing for D2Audio’s
Class-D amplifier solutions. A variety of Reference Designs from
Intersil D2Audio Corporation include specific signal flows
designed for their applications, supporting today’s design
features. Support is also provided for future planned features,
with little or no additional hardware or logic to enable new
features. The signal flow, digital audio I/O, and amplifier
hardware control support is handled completely by the DAE-6
firmware.
The products are targeted at high-volume Home Theater in a Box
(HTiB), Multimedia, Soundbar, and similar solutions, where rich
features and cost-effective quality audio are required to meeting
demands of current consumer electronics markets.
The DAE-6 devices are completely pin-compatible with the DAE-3
devices, allowing full flexibility for function vs cost trade-off,
providing cost-effective solutions for applications of varying
end-user features and capabilities.
Target Performance

that includes or exceeds:
• >110 dB SNR/Dynamic Range System Support
• <0.06% THD+N at Full Scale at 1kHz
• 20Hz to 20kHz Audio Frequency Response
• Scalable Amplifier Power Control Capability
• Discrete Component and Integrated Power Stages using
Full-Bridge, Half-Bridge, and BTL Output Topologies
• Encrypted Code Loads and Unique Decryption for each IC Part
Number
• Support for all Standard Audio Data Delivery Formats and
Protocols Employed in the Target Markets
• The Delivery Formats Include: I²S, Left-Justified, Time-Division
Multiplexed (TDM), S/PDIF, DSD, HDA, 2-Channel Analog
Application Markets
The powerful DSP coupled with flexible peripherals and excellent
signal processing hardware results in a chip for solutions that
cover many markets. All are characterized by the need for
complex signal processing and high audio channel count. Typical
applications include a wide variety of cost sensitive but
feature-demanding performance such as in:
• Multimedia Speaker Solutions
• Multi-Driver (Bi-Amp, Tri-Amp) Speaker Arrays
• Home Theater Systems with Compressed Audio Decoder
• Soundbar System Solutions
• Set-Top Box Solutions
• Low-Cost Virtualized Stereo, 5.1, 7.1, and 9.1 AVR Systems
• MRDA distributed and networked audio systems with multiple
powered channels
• Aftermarket/OEM Automotive Amplifiers
