FG-23629-D65 Ultrasonic Applications for Knowles Electret and MEMS Microphones

PublishTime：2022-02-24

■While in most cases Knowles microphones are used for receiving audible signals, several models are also used in ultrasonic applications. Knowles production line testing typically takes place at several frequencies up to 10kHz. Therefore the microphone specifications are also written with performance data up to 10kHz but not beyond. While this is sufficient for ensuring the quality of the outgoing microphone, it does not mean that the microphone is limited to 10kHz in practice. In this application note typical performance data up to 100kHz is given for the microphone models most commonly used in ultrasonic applications
