Low Power MEMS Silicon Microphones

Knowles has launched the SP series of micro electro-mechanical system (MEMS) silicon microphones. These microphones consist of an acoustic sensor, a low noise input buffer and either a sigma-delta modulator or output amplifier. Design variables include ever-smaller sizes, lower profiles, mounting options, increased output capacities and digital audio options that eliminate analog noise.

Typical applications include cellphones, smart phones, laptop computers, sensors, digital still cameras, portable music recorders and other portable electronic devices.
