be used in conjunction with the STEVAL-MKI126Vx (Smart Voice) kit, containing 4 MP45DT02 digital MEMS microphones.</p> <p>The coupon concept allows easy performance testing of ST MEMS microphones. When inserted in the Smart Voice board, it is possible to detach the single PCBs hosting each microphone.</p> <p>The MP45DT02 is a compact, low-power, top-port, omnidirectional, digital MEMS microphone. The MP45DT02 is built with a sensing element and an IC interface with stereo capability. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors.</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>4 x MP45DT02 top port digital MEMS microphones</li> <li>Daughterboard to be used withSTEVAL-MKI126Vx kit</li> <li>Vsupply from 1.64 V to 3.6 V</li> <li>120 dBSPL acoustic overload point</li> <li>Omnidirectional sensitivity</li> <li>PDM single-bit output</li> <li>61 dB of SNR</li> <li>Sensitivity -26 dBFS</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Application Note</h4> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/DM00061574.pdf" target="_blank">AN4146: STSmartVoice demonstration board STEVAL-MKI126Vx (pdf)</a> </div> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/DM00067272.pdf" target="_blank">AN4184: Microphone coupon boards STEVAL-MKI129Vx /MKI155Vx based on digital microphones (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/DM00070854.pdf" target="_blank">AN4211: Guidelines for soldering MEMS microphones (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00025467.pdf" target="_blank">DS7162: MEMS audio sensor omnidirectional digital microphone DS7162: MEMS audio sensor omnidirectional digital microphone (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">License Agreement</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/legal/legal_agreement/license_agreement/EvaluationProductLicenseAgreement.pdf" target="_blank">Evaluation products license agreement (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Product Brief/Fact sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/data_brief/DM00072699.pdf" target="_blank">DB1854: Microphone coupon board based on the MP45DT02 digital MEMS microphone (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Bill of Materials</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/bill_of_materials/steval-mki129v1_bom.pdf" target="_blank">STEVAL-MKI129V1 BOM (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment "> <i class="fal fa-file-archive"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/layouts_and_diagrams/board_manufacturing_specification/steval-mki129v1_gerber.zip" target="_blank">STEVAL-MKI129V1 gerber files (zip)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/layouts_and_diagrams/schematic_pack/steval-mki129v1_schematic.pdf" target="_blank">STEVAL-MKI129V1 schematics (pdf)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: microphone, MP45DT02, microphone_amplifier, mems, audio_video, stm, analog_demo_boards</div>
