Single-chip audio processor goes portable

The BelaSigna 250 audio processing system is targeted at a variety of applications, including communication devices, speciality headsets, remote sensors and other portable equipment.

New from AMI Semiconductor (AMIS), the BelaSigna 250 audio processing system is targeted at a variety of applications, including communication devices, speciality headsets, remote sensors and other portable applications requiring audio compression and recording, sound management or echo and speech processing functionality.

The BelaSigna 250 is a complete audio solution with a highly integrated design that includes analogue to digital and digital to analogue convertors, filters, amplifiers and power management, reducing the need for external components.

The result is a reduced bill of materials, reduced assembly costs and a simplified design process that saves valuable integration time and improves time to market.

In addition, its unique parallel processing architecture enables power efficiency without sacrificing performance, resulting in longer operation and standby times and thus, increased battery life.

The BelaSigna 250 is the optimal solution for audio applications and enables extensive flexibility without sacrificing power consumption, allowing device designers to use the same platform for a wide range of products with different feature sets.

Additionally, the BelaSigna 250 offers excellent compact audio performance allowing for even smaller industrial designs.

"The audio industry is adopting new advanced and integrated technologies into more basic products and this trend is facilitated by the availability, affordability and targeted integration of technologies".

"The BelaSigna 250 will enable a diverse market with practical, deployable advanced audio processing features", said Dave Coode, audio products manager at AMI Semiconductor.

Supporting audio processing software is available from AMIS and its partners to suit many applications.

User-friendly development tools are also available to simplify and speed up custom development and testing of advanced software.

The BelaSigna 250 is packaged in a miniature chip-scale 48-pin package.

Volume quantities will be available early 2006.
