OBSOLETE PRODUCT — ADAV4101:  Audio Processor for Advanced TV

The ADAV4101/ADAV4201 are part of a family of high performance analog and digital input/output audio processors.

The audio processor, by default, loads a dedicated audio flow that incorporates full matrix switching (any input to any output), automatic volume control that compensates for volume changes during advertisements or when switching channels, dynamic bass, a multiband equalizer, and up to 200 ms of stereo delay memory for audio-video synchronization.

Alternatively, Analog Devices offers an award-winning graphical programming tool (SigmaStudio™) that allows for custom flows to be quickly developed and evaluated. This allows the creation of customer-specific audio flows, including the use of Analog Devices library of third-party algorithms.

The analog input/output integrates Analog Devices proprietary continuous-time, multibit Σ-Δ architecture to bring a higher level of performance to ATV systems, required by third-party algorithm providers to meet system branding certification. The analog input is provided by 95 dB dynamic range (DNR) ADCs, and analog output is provided by 95 dB DNR DACs.

The main speaker outputs can be supplied as a voltage out from the integrated DAC channels (ADAV4101) or as a digitally modulated PWM stream to support digital amplifiers (ADAV4201).

The ADAV4101/ADAV4201 include multichannel digital inputs and outputs. In addition, two of the digital input channels can be routed through integrated SRCs, which are capable of supporting any arbitrary sample rate from 5 kHz to 50 kHz.

Comprehensive documentation, which provides detailed operation guidelines and register map information, is available upon request from AV.Products@analog.com.

Applications

  • General-purpose consumer audio postprocessing
    - Home audio
    - DVD-Rs
    - Home theater in a box (HTIB) systems and DVD receivers
  • Audio processing subsystems for DTV-ready TVs
  • Analog broadcast capability for iDTVs
