MEMS Microphones for Audio Applications

MEMS microphones are essentially condenser microphones with the diaphragm etched into silicon. Because of the limited range of motion of the silicon diaphragm, MEMS microphone chips usually contain built-in amplification and ADCs. Once the signal is digitized, noise ceases to be a serious problem. Learn More
