Product Description
Miniature Silicon MEMS (Micro Electro Mechanical System) omni-directional Microphone with single-ended
analog interface designed for automated reflow soldering assembly as SMD (Surface Mounted Device)
component. It is an alternative to conventional ECMs (Electret Condenser Microphones).
Due to its robust design with a metallic lid and monolithic integrated EMI-blocking capacitors and utilization of
Silicon MEMS technology, the SMM310 shows high immunity to EMI (Electromagnetic Interference) and heat.
The capped Chip-On-Board package solution contains the micromechanical sensor chip and an amplifier chip.
The RoHS-compliant device has a size of 4.72 x 3.76 x 1.25 mm
