STMicroelectronics MP23AB02B MEMS microphones maintain ultra-low distortion of less than 10%, which helps improve the quality of calls and recordings in smartphones and wearables in noisy environments.

The acoustic overload sound pressure level is 125dBSPL, the signal-to-noise ratio is 64dBA, and the size is only 3.35mm x 2.5mm x 0.98mm. Compared with its ultra-fine size, this microphone has market-leading superior performance, thanks to STMicroelectronics. Dedicated preamplifier design. The amplifier prevents saturation of the output signal, especially when the background noise is high, for example, in concert halls, bars and clubs, or when the user speaks loudly near the microphone , the amplifier's anti-saturation effect is even better. In addition, omnidirectional sensitivity ensures excellent overall microphone performance for more use in mobile applications.

The MP23AB02B is easy to design into the customer's system. A single-ended output is generated using a single supply voltage of 1.8V-3.6V. The 150μA typical operating current ensures ultra-low power consumption in the microphone, simplifying thermal management and maximizing battery life. The new microphone's wide operating temperature range of -40°C to +85°C ensures excellent operational stability and reliability.

The MP23AB02B is available now in volume and is available in a RHLGA 3-lead metal cap package.
