STMicroelectronics MP34DT04TR is a digital MEMS microphone designed for high-performance audio capture. This omnidirectional microphone outputs a Pulse Density Modulation (PDM) digital signal, enabling direct interfacing with modern digital audio processors. With a wide operating voltage range of 1.6 V to 3.6 V and a typical supply current of 700 µA, it offers excellent power efficiency. The MP34DT04TR features a frequency response from 100 Hz to 10 kHz and a sensitivity of -26dB ±3dB at 94dB SPL, coupled with a signal-to-noise ratio of 64dB. Its compact 4.00mm x 3.00mm footprint and 1.20mm height make it suitable for integration into space-constrained applications across consumer electronics, automotive, and industrial sectors. The component is supplied on a tape and reel for automated assembly, utilizing solder pad termination.
