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.

“Hearing aids represent an application ideally suited for the advantages MEMS
microphones offer including small size, stability, and very low power
consumption,” said Pat O’Doherty, vice president for the Healthcare Group,
Analog Devices. “However, MEMS microphones have not offered the EIN
performance levels that meet stringent hearing aid standards until now. 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.
