Norwood, MA (02/14/2012) - NORWOOD, Mass. — Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal processing applications, introduced today the high-performance ADMP504 the industry’s lowest-noise MEMS microphone. Delivering an SNR (signal-to-noise ratio) of 65-dBA, or 29-dBA EIN (equivalent input noise), the ADMP504 provides the same SNR performance as an array of two individual 62-dB SNR microphones. In addition, the ADMP504 provides an extended frequency response up to 20 kHz and a high PSR (power-supply-rejection) of 70 dBV. With this performance, the ADMP504 addresses the demanding requirements found in many industrial, professional audio and video conferencing applications. The new microphone leverages ADI’s patented MEMS technology and audio signal processing expertise and is available in a thin 3.35 mm × 2.50 mm × 0.88 mm surface-mount package.

Global shipments of MEMS microphones rose to 1.3 billion units in 2011, up 82 percent from 704 million in 2010 driven primarily by handsets, according to IHS.
“ADI’s high-performance MEMS microphones have earned market acceptance since they entered the market in 2008, particularly in smartphones and media tablets,” commented Jérémie Bouchaud, director and principal analyst, MEMS and sensors, IHS. “With further performance improvements, ADI is poised to enable many new and innovative applications in other markets such as industrial equipment monitoring and building security.”
The ADMP504 is a surface mount MEMS microphone that is reflow solder compatible with no sensitivity degradation. The sensitivity specification of -38 dBV is well suited for many codecs and discrete signal chain components. The high SNR of 65 dBA, or 29 dBA EIN, enables far-field audio-capture applications, as well as those using multi-microphone “beam-forming” algorithms. Low current consumption of < 180 μA (typ) with a power supply voltage of 1.6 V to 3.3 V extends battery life for portable applications.

The ADMP504 is function- and pin-compatible with the ADMP404 providing designers with an easy upgrade path. Additional 65-dB SNR MEMS microphones are planned for this family, including a PDM (pulse-density-modulation) output version.
