National Semiconductor Introduces New Microphone Technology

(NATIONALSEMICONDUCTORCORPORATION) announced the introduction of a new microphone technology that enables electret condenser microphones (ECMs) to add digital voice output capabilities, once again creating a new dimension for electronic consumer products such as microphones. Electronic consumer product manufacturers have always avoided using digital voice technology in their products, because the electret condenser microphone with digital voice function is not only expensive but also bulky. National Semiconductor's new technology allows the microphone to be digitally modulated and gained internally, which not only greatly improves the sound, but also solves the volume and cost problems. National Semiconductor has integrated a variety of different components and streamlined its wiring design, and finally successfully developed this "digital voice microphone" technology, which not only reduces the overall cost of the system, but also minimizes the size of the product.

ErrollDietz, Product Director, National Semiconductor's Amplifier Products Division, said: "National Semiconductor has been committed to developing innovative signal conditioning technology, which is the amplifier product development strategy we have been pursuing. Today's press release shows that we will continue to implement this strategy. Because of this The mixed-signal chip is so small that it can be built into the currently used electret condenser microphone. After this technology is introduced, it is believed that the microphone can add digital voice function in the near future."

National Semiconductor introduced the LMV1012 and LMV1014 analog "microphone amplifier" chips earlier, and digital voice technology is another innovative contribution of the company. This new technology can dramatically improve the acoustics and sensitivity of 2-wire and 3-wire electret condenser microphones, making the field-effect transistor (JFET) commonly used in the past decades gradually phased out, and this market is also structurally The transformation. Adding a digital output to the microphone will be the next step in amplifier technology, and the world's first digital output feature ensures that the 4-wire electret condenser microphone can provide its own gain. This new technology is suitable for mobile phone microphones, personal digital assistants and other portable microphone applications.

ErrollDietz said: "National Semiconductor has been committed to providing digital audio systems for communications and computing products in the consumer market. In order to achieve this goal, we are working with major microphone suppliers to improve the performance of digital electret condenser microphones. We also plan to use this technology to manufacture products specifically designed for our customers and to ensure that new products can be launched before the end of this year.”
