The MP45DT01 MEMS, digital-output stereo microphone enables advancements in sound quality by providing omni-directional sensitivity to detect and filter out background noise. Sound quality can be further improved by incorporating multiple microphones in one device. According to the company, MEMS microphones meet price points set by the traditional electret condenser microphones while boasting superior reliability and robustness. The MP45DT01 uses sensor technology from OMRON that is inherently less susceptible to mechanical vibration, temperature variations, and EMI. Price for the MP45DT01 is $1 each/10,000.
