Micronas GmbH launched a new family of single-chip audio processors that contains two seriesthe MAP 440xA with analog outputs, and the MAP 460xA with digital pulse width modulation outputs.

According to the company, the Micronas Audio Processor (MAP) family is designed to reduce the system cost of modern consumer audio applications like home theater systems, surround sound AV amplifiers, Home Theater in a Box and mini/midi HiFi components with 2.0 to 5.1 channel speaker support, but also the fast-growing market of next-generation in-car audio systems.

Micronas added that for the first time a single, compact mixed-signal IC integrates all the building blocks required for a consumer audio system with various audio processing capabilities. Arranged around a high performance DSP core optimized for audio processing, are analog inputs and outputs together with the corresponding high-quality ADCs and DACs, as well as digital I?S audio ports. The system designer can choose between analog outputs driving classic power amplifier stages or purely digital ports. These outputs, equipped with the company's Hi-Resolution PWM technology, are able to feed "state-of-the-art class-D digital amplifiers."

"The well balanced system architecture of the ICs, which merges all the required analog functions with a dedicated pre-programmed audio DSP core, provides a rich set of features at comparatively low cost," said Stefan Hepp, director of marketing consumer audio for Micronas. "It makes system design easy, typically replacing a whole set of ICs by one monolithic chip."

All MAP 440/460xA ICs are pin and software compatible. They come in a QFP80 package with 0.8mm pitch or QFP100 (0.5mm) pitch package. Evaluation boards, as well as design-in support services are available.
