STMicroelectronics Omni-Directional Surface Microphone Condenser 1dB 3.6V dc MP23DB01HPTR

STMicroelectronics MP23DB01HPTR is an ultra-compact, low-power, omnidirectional digital MEMS microphone condenser designed for high precision acoustic sensing in various electronic applications. Operating at a standard voltage of 3.6V dc, this surface mount device provides digital PDM output suitable for stereo audio configurations, making it ideal for consumer and industrial audio devices.

The microphone features a capacitive sensing element fabricated using a specialized silicon micromachining process, combined with an integrated CMOS IC providing the digital interface. Its ultra-small height of 0.98mm and bottom-port design make it compatible with space-constrained PCB layouts.

With a sensitivity of 1dB and a signal-to-noise ratio of 65.5 dB, it accurately captures audio signals while maintaining very low distortion thanks to its high acoustic overload point of 135 dBSPL. The device supports multiple power modes, including sleep (2 μA), low-power (285 μA), and performance (800 μA), allowing efficient power management in portable and battery-operated equipment.

The operating temperature range from -40°C to 85°C ensures reliable operation in diverse environmental conditions. The device is RoHS and Ecopack compliant and EMI shielded, suitable for industrial, laboratory, consumer electronics, and audio processing applications.
