P iezoelectric M EM S M icrophone 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
