GENERAL DESCRIPTION
The ADAV400 is an enhanced audio processor. Integrating high
performance analog and digital I/Os with a powerful, audio-
specific, programmable core enables designers to differentiate
their products through audio performance.
The audio processing core is based on Analog Devices SigmaDSP
technology featuring full 28-bit processing (56-bit in double
precision mode), a sophisticated, fully programmable dynamics
processor, and delay memory.
This technology allows the system designer to compensate for
real world limitations of speakers, amplifiers, and listening
environments. This compensation results in a dramatic
improvement of the perceived audio quality through speaker
equalization, multiband compression and limiting, and third-
party-branded algorithms.
The analog I/O integrates Analog Devices proprietary continuous
time, multibit, sigma-delta (Σ-Δ) architecture. This integration

brings a higher level of performance to systems that are
required to meet system branding certification by third-party
algorithm providers. The analog inputs feature a 95 dB dynamic
range stereo ADC fed from a four-stereo input mux. The four
stereo analog outputs are each driven by a 95 dB dynamic range
DAC. A dedicated headphone channel is included with
integrated amplifiers.
The ADAV400 supports multichannel digital inputs and outputs.
An integrated SRC on one channel provides the capability to
support any input sample rate in the range 5 kHz to 50 kHz,
synchronizing this input to the internal DSP engine.
The ADAV400 is supported by a powerful graphical programming
tool that includes blocks such as general filters, EQ filters, dynamics
processing, mixers, volume, and third-party algorithms for fast
development of custom signal flows.
