Analog and Digital MEMS Microphone Design Considerations

Analog and Digital MEMS Microphone Design Considerations

Overview

Microphones are transducers that convert acoustic pressure waves to electrical signals. Sensors have become more integrated with other components in the audio signal chain, and MEMS technology is enabling microphones to be smaller and available with either analog or digital outputs. Analog and digital microphone output signals obviously have different factors to consider in a design. I will examine the differences and design considerations to consider when integrating analog and digital MEMS microphones into a system design.
