Smallest MEMS Microphone Designed for Hearing Aid Applications Features Low Equivalent Input Noise (EIN) and Power Consumption Analog Devices ADMP801 MEMS microphone delivers 27 dBA EIN, consumes only 17 µA at 1 V supply, and is available in a 7.3 mm³ package. Business Wire NORWOOD, Mass. -- March 26, 2013 Analog Devices, Inc. (NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, introduced today a high performance MEMS microphone developed specifically for hearing aid applications. When compared to legacy solutions like electret condenser microphones (ECMs), the ADMP801 is not only smaller in size at only 7.3 cubic millimeters, but also offers greater performance stability over time, temperature, and environmental changes, produces very low equivalent input noise (EIN) at 27 dBA SPL (sound pressure level), and consumes only 17 µA at 1Vsupply -- a fraction of the power consumed by traditional ECMs. The ADMP801 MEMS microphone is available in a tiny surface-mount package measuring only 3.35 mm x 2.50 mm x 0.98 mm that is reflow-solder-compatible with no sensitivity degradation.

The ADMP801 MEMS microphone offers noise performance, package size, and phase and gain stability that is very desirable for advanced hearing aids that incorporate beamforming to facilitate sound or voice localization.” More About the ADMP801 Omnidirectional MEMS Microphone The ADMP801 is a high quality, ultralow power, analog output, bottom-ported, omnidirectional MEMS microphone designed specifically for hearing aid applications.It is fully pick-and-place and reflow compatible, offering an option to save on cost using a mechanized assembly process as compared to ECMs that require manual assembly processes. The device offers excellent environmental and temporal stability, and multiple ADMP801 MEMS microphones can be configured in an array to form a directional response, facilitating sound of voice localization.
