Overview:
MEMS microphones with the capability to capture very high sound pressure acoustic waves (loud noises) with high fidelity hold the potential not only to improve user experience in audio capture, but also make acoustic detection viable for a range of applications that might have previously been unsuitable for such methods. Coupling high SPL performance with a low noise floor (expressed by high SNR) yields microphones with a very wide dynamic range. Such wide dynamic range microphones are particularly compelling when considered alongside the benefits of MEMS technology. We will discuss specific design considerations for such wide dynamic range microphones and the various applications that might benefit from such high performance.

Who should attend:
Electrical or acoustics engineers with microphones in their design. This webcast will be valuable to long time users of microphones who may not yet be familiar with MEMS microphones and also to electrical engineers with little or no previous experience with microphones in particular. Engineers working on acoustic sensing applications in extreme environments (outdoors, hard to replace equipment, loud environments, etc.) will be particularly interested. Sample applications might include IP cameras, security panels, flow monitoring, photoacoustic gas detection, or fire/police radios.

Presenters:
Jerad Lewis, MEMS Microphone Applications Engineer, Analog Devices

Jerad Lewis is a MEMS microphone applications engineer at Analog Devices. He joined the company in 2001 after getting his BSEE from Penn State University. Since then, he's supported different audio ICs, such as SigmaDSPs, converters, and MEMS microphones. He is currently also pursuing a M.Eng. in Acoustics at Penn State University.

Paul Schreier, Product Marketing Manager, Analog Devices
Paul Schreier is a product marketing manager at Analog Devices. Prior to joining ADI in 2011, he has held various marketing and sales positions at major semiconductor vendors working with products in power management and microcontrollers. He holds a BS Computer Engineering from the University of Nebraska and an MBA from Boston College.
