The SigmaDSP® Multichannel Audio Processor with Embedded 2ADC/8DAC Codec ADAV400 Rev. PrG is a chip with multi-channel audio processing capabilities. It features fully programmable audio digital signal processing (DSP) for enhanced sound processing, SigmaStudio™ graphical programming tool for fast development of custom signal flows, easy implementation of third party audio algorithms, scalable digital audio delay line, and high performance integrated analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).
The ADAV400 is an enhanced audio processor integrating high-performance analog and digital I/O with a powerful programmable core based on SigmaDSP technology. It features full 28-bit processing, a dynamics processor, and delay memory to compensate for real-world limitations of speakers and listening environments.
The device includes proprietary continuous-time multibit sigma-delta architecture for the analog inputs (95 dB dynamic range ADC) and outputs. It supports multichannel digital I/O modes and features an integrated sample rate converter (SRC) supporting rates from 5 kHz to 50 kHz.
