Analog MEMS microphone
Wolfson Microelectronics
The WM7110 is a compact high Signal to Noise ratio silicon analogue microphone for use in consumer applications requiring low power consumption, typically 140µA, and excellent signal quality. It offers low THD, good linearity and a flat phase response to offer excellent sound quality. Using Wolfson Microelectronics’ unique CMOS/MEMS membrane technology it delivers high reliability and performance in a miniature low profile package.
The WM7110 can withstand the high temperatures needed for automated reflow solder assembly, which can damage conventional microphones. Automated pick and place equipment can be used for assembly on to circuit boards.
