Wolfson's Audio Codec Provides Leading Power Savings for Mobile Devices.Business Editors/High-Tech Writers SAN DIEGO San Diego (săn dēā`gō), city (1990 pop. 1,110,549), seat of San Diego co., S Calif., on San Diego Bay; inc. 1850. San Diego includes the unincorporated communities of La Jolla and Spring Valley. Coronado is across the bay. & EDINBURGH, Scotland--(BUSINESS WIRE)--June 2, 2003 High Performance Audio Sub-System Provides Superior Audio Features In Smartphone and Handheld Consumer Devices Wolfson Microelectronics today enhanced its mobile device IC offering with the introduction of an ultra low-power, single-chip design with the company's leading audio sub-system codec (1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV, capability. The highly integrated WM9711L IC, similar to the WM9712L released earlier this year, is designed for use in latest generation of handheld computing and communication devices. The WM9711L uses the AC'97 audio interface to eliminate hidden extra power consumption often found in older codec designs and avoids CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. loading for the best possible full split-rate sample rate support. The new codec can be connected directly to mono or stereo headphones Head-mounted speakers. Headphones have a strap that rests on top of the head, positioning a pair of speakers over both ears. For listening to music or monitoring live performances and audio tracks, both left and right channels are required. and microphones or mono speakers to reduce total component count in a system. Headphone See headphones. output and five GPIO GPIO General Purpose Input/Output GPIO General Purpose Input Output pins allow seamless integration with wireless communication devices or other digital systems. Audio mixing features include a superior bass boost function that provides more bass gain at low input levels. "The WM9711L makes it possible to not only make a phone call, but record the call, make voice notes, record MP3 files and play them during the call," said David Milne, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. and managing director for Wolfson. "No other competing product offers the functionality of this component." The WM9711L cuts power consumption by more than half compared to similar devices on the market, running from supply voltages between 1.8V and 3.6V and core voltages down to 1.42V. This has been achieved through the use of low-power silicon technology and power efficient design of the analog circuit blocks. Price and Availability The WM9711L operates on 1.8V to 3.6V supplies and is supplied in a leadless, chip-scale QFN QFN Quad Flat No-Lead QFN Queen Fan Newsletter (rock band) QFN Quad Flat No Leads package with 7 x 7mm-body size. It is available now for $2.46, US, in quantities of 10,000 pieces. Device drivers for selected platforms and operating systems are also available. For sales information email: usa@wolfsonmicro.com.
