STMicroelectronics MP34DB01TR is a digital PDM (Pulse Density Modulation) MEMS microphone with an omnidirectional polar pattern. This silicon-based acoustic sensor operates within a frequency range of 20 Hz to 20 kHz, delivering a sensitivity of -26dB ±3dB at 94dB SPL. Designed for efficient operation, it features a low supply current of 650 µA and a wide operating voltage range of 1.64 V to 3.6 V, with a rated voltage of 1.8 V. The MP34DB01TR offers a signal-to-noise ratio of 62.6dB. Its compact form factor, measuring 4.00mm x 3.00mm with a height of 1.10mm, is suitable for space-constrained applications. The component is supplied in a Tape & Reel (TR) package with solder pad terminations for robust mounting. This microphone is utilized in various applications including consumer electronics, voice-activated devices, and audio capture systems.
