iMEMS Digital and Analog Microphones Deliver Industry's Best Signal-to-Noise Ratio and Frequency Response
Better audio performance is a key differentiator in consumer electronics devices such as Bluetooth headsets, laptop PCs, cell phones, and digital video cameras. Today's ECM technology poses an obstacle to meeting these needs.
ADI's ADAV4622 is a highly integrated audio processor system chip for advanced TV applications. It includes a worldwide analog broadcast decoder, multichannel analog and digital input and output channels, integrated digital Class-D output, and a configurable audio processor that supports ADI's SigmaStudio® graphical user interface (GUI) audio design tool. The ADAV4622 includes a number of features to address the audio system design challenges currently facing TV designers. For example, pop and click issues due to power-up and power-down of the audio subsystem are resolved with a DAC and Class-D architecture that eliminates DAC and Class-D sharp transitions during the power sequence. In addition, the ADAV4622 integrates hardware accelerators (requiring no DSP overhead) that enable smooth switching between various sources and levels without risk of the associated audio artifacts. Also available is a full library of supporting audio algorithms including automatic volume control, bass enhancement, speaker and chassis equalization, dynamic range control, and many popular third-party algorithms.
