The STMicroelectronics MP23AB02B MEMS microphone maintains ultra-low distortion at less than 10% up to very high external sound-pressure levels, enabling equipment such as smartphones and wearable devices to perform better when placing calls or recording audio in loud environments.

The key is ST’s dedicated pre-amplifier design, which prevents saturation of the output signal even when background-noise levels are high, such as in concert venues, bars or clubs, or if the user is speaking loudly close to the microphone. In addition, omnidirectional sensitivity ensures excellent overall performance and versatility in mobile applications.

The MP23AB02B is in volume production now in the RHLGA 3-lead metal-cap package, priced from $1.00 for orders of 1,000 pieces.
