Overview

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. With acoustic overload level of 125 dBSPL and signal-to-noise ratio of 64 dBA, the 3.35 mm x 2.5 mm x 0.98 mm microphone delivers market-leading performance for its minuscule size. 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 also easy to design-in. It operates from a single supply voltage in the 1.8 V - 3.6 V range and generates a single-ended output. Typical operating current of 150 µA ensures ultra-low power consumption, which simplifies thermal management and helps maximize battery life. Specified over the extended operating-temperature range from -40°C to +85°C, the microphone also ensures outstanding ruggedness and reliability.
