The ADAV4601 Rev. B is a high-performance audio processor from Analog Devices that supports 24-bit ADC and DAC, and has 94 dB DNR performance, which can be used to enhance ATV audio effects.
The Analog Devices ADAV4601 is an enhanced audio processor designed for advanced TV (ATV) applications, supporting both digital and analog baseband audio. By default, it loads a dedicated TV audio flow that includes full matrix switching, automatic volume control, dynamic bass, a multiband equalizer, and up to 200 ms of stereo delay memory for audio-video synchronization. Alternatively, the device supports custom audio flows developed using the SigmaStudio graphical programming tool.
