Microphone Chips Information

microphone chips

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

Applications

Common applications include smart phones, tablets, headsets, cell phones and other handheld electronic devices.
