Hot-selling and scarce ADAV400KSTZ Audio Codec with Embedded SigmaDSP Processor QFP80 spot stock

Product Descriptions

The ADAV400 is an enhanced audio processor. Integrating highperformance analog and digital I/Os with a powerful, audiospecific, programmable core enables designers to differentiatetheir products through audio performance .

The audio processing core is based on Analog Devices SigmaDSPtechnology featuring full 28-bit processing (56-bit in doubleprecision mode), a sophisticated, fully programmable dynamicsprocessor, and delay memory.

This technology allows the system designer to compensate forreal world limitations of speakers, amplifiers, and listeningenvironments . This compensation results in a dramaticimprovement of the perceived audio quality through speakerequalization, multiband compression and limiting, and thirdparty-branded algorithms .

The analog I/O integrates Analog Devices proprietary continuoustime, multibit, sigma-delta (Σ-Δ) architecture . This integration​ brings a higher level of performance to systems that arerequired to meet system branding certification by third-partyalgorithm providers . The analog inputs feature a 95 dB dynamicrange stereo ADC fed from a four-stereo input mux . The fourstereo analog outputs are each driven by a 95 dB dynamic rangeDAC . A dedicated headphone channel is included withintegrated amplifiers .
