PUI Audio Microphone, 300Ω Impedance, Omni Directional Pattern - AMM-2742-T-R
This microphone is a Compact MEMS sensor designed for capturing sound across a broad audible range in embedded and instrumentation contexts. It operates at low supply voltages and is suited to electronic systems where small form factor and wide frequency coverage are required. The device connects via a pin-style Interface and is built to meet contemporary material restrictions for industrial use.
Features and Benefits:
• Omni-directional pick-up providing uniform coverage for multi-source capture
• 300Ω impedance enabling predictable interfacing with preamps
• -42 dB sensitivity for Detectable signal levels in controlled environments
• 20 kHz frequency response preserving high-frequency content up to the audible limit
• 160 dB maximum SPL allowing recording of very loud sound events
• Operates from 1.5 to 3.6V for compatibility with low-voltage designs
