AUDIO-1-KIT

AUDIO-1-KIT MEMS Microphone, ESD Notch Filter, & Noise Suppression Filter Sample Kit PRODUCT HIGHLIGHTS AUDIO-1-KIT combines TDK InvenSense MEMS microphones with TDK brand’s noise suppression filters (MAF series) and ESD notch filters (AVRF series) specifically designed to combat typical issues in audio lines, while offering additional benefits such as improving reception sensitivity in cellular or Wi-Fi communication. Figure 1 Figure 1 shows an example of noise countermeasures in microphone lines using MAF series noise suppression filters and AVRF series ESD Notch Filters, and their effectiveness. It can be clearly seen that in filter circuits that use both MAF and AVRF series products together, the insertion loss in cellular bands is even larger than in circuits that use only MAF products.
