VM3000 Low Noise PDM Digital Bottom Port Piezoelectric MEMS Microphone PRELIMINARY DATASHEET GENERAL DESCRIPTION The VM3000 is a high performance, low noise digital MEMS microphone. It features a PDM output enabling multiplexing of two microphones on a single data line. The digital output has high immunity to RFI and EMI providing designers with more flexibility in the position of the mics and the routing of their wires in system. The VM3000 has an industry standard 3.5x2.65x1.3mm package. The microphone is solder reflow compatible with no sensitivity degradation. It operates in environmentally harsh surroundings being dust and moisture resistant. FEATURES Digital Output, Pulse Density Modulation (PDM) Less than 1A current consumption in Sleep mode Ultra-fast startup, 200 Sec, from all modes Dust and moisture resistant, IP58 Flat Frequency Response Sensitivity Matching Supports Dual Multiplexed Channels on DATA line BLOCK DIAGRAM RFI and EMI robust Industry standard 3.5 x 2.65mm LGA package footprint APPLICATIONS Beamforming Arrays Smart Home Devices Outdoor Applications Wearables IP Security Cameras ORDERING INFORMATION TYPICAL APPLICATION CIRCUIT Product Package Description Quantity VM3000AA 13 Tape and Reel 5,000 Page 1 of 13 Document Name: VM3000 Datasheet Vesper reserves the right to alter the datasheet specifications without notification.
