Description

 

Microphone chips are integrated circuits (IC) microphones and are usually mounted directly to a circuit board.

 

microphone chipsA pressure-sensitive diaphragm is etched directly into a silicon chip by MicroElectrical-Mechanical System (MEMS) techniques, and is usually accompanied with integrated preamplifier.

 

Most MEMS microphones are variants of the condenser microphone design. Often MEMS microphones have built in analog-to-digital converter (ADC) circuits on the same CMOS chip making the chip a digital microphone and so more readily integrated with modern digital products.microphone chips
