ADAV400

The ADAV400 is an enhanced audio processor. Integrating high performance analog and digital I/O 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 ADAV400 analog I/O integrates Analog Devices proprietary continuous time, multibit, sigma-delta (-) 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 ADC fed from a 4-stereo input mux. The main speaker outputs can be supplied as a voltage output from the integrated 95 dB dynamic range DAC channels. A dedicated headphone DAC with integrated amplifiers and additional auxiliary analog outputs is also available.

The ADAV400 supports multichannel digital inputs and outputs. An integrated SRC on one channel provides the capability to support any input sample rates in the range from 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.
