Features SMD MEMS microphone for automated surface mount assembly Reflow soldering up to 260 C (lead free) High long-term temperature stability Stable sensitivity over power supply range of 1.5-3.3 V Low current consumption of 80 µa Excellent power supply rejection of -55 db High integrated immunity to EMI RoHS-compliant package with small footprint and low height of 1.25 mm Applications The is designed for Mobile Phones (Handsets, Headsets) Consumer (Game Consoles, PDA s) Computer (Personal Computers, Notebooks) Cameras (Digital Still Cameras, Video Cameras) 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 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 3.
