ADI offers a portfolio of analog & digital audio & video distribution/processing products ensuring complete signal chain compatibility.
Blackfin DSP enables:
Audio post processing
AM/FM/DAB processing
Multi-media connectivity
Bluetooth / Speech recognition
Target Applications Hands-free connectivity, active noise cancellation,
premium audio systems.
Sigma – Delta architecture provides high dynamic range and SNR enabling highest quality premium audio systems. ADI brings its industry-leading position in converter
technology to both the head unit and trunk amplifier segments.
24-bit resolution / 192KHz Fs are standard throughout the majority of product portfolio.
Next generation architecture combines high performance & channel count with industry-leading power consumption. Reduced power enables higher performance at
extended automotive temperatures.
Pin-compatible roadmap to SigmaDSP-enabled devices increases design flexibility. Incremental audio processing power can be added to
end product without modifying hardware design.
Industry standard interfaces and control circuitry minimize design complexity. Glueless connection to ADI’s Blackfin, SHARC, and
SigmaDSP processors.

Target Applications Audio Post-Processing & signal routing in automotive
head-units, amplifiers, navigation, and DVD-based entertainment systems.
Application-tuned architecture enables high quality audio at low overall system cost. Hardware and software environment were developed
strictly to meet the requirements of next generation audio applications.
Award – Winning Sigma Studio Development Environment simplifies the audio system development challenge. User –friendly GUI plus large library of optimized
audio processing building blocks enables the software engineer to focus on adding value to the end product – not spending time writing DSP code.
Hardware features are optimized for audio applications reducing the need for external support components. Integrated sample rate converters and high
performance A/D – D/A’s leverage ADI core capabilities.
Sophisticated Signal Routing Unit (SRU) provides flexibility in the number and type of audio input sources.
