Product Description
STMicroelectronics MP34DT05TR-A digital MEMS Microphone is engineered for precise acoustic sensing in diverse applications including consumer electronics, industrial sensors, and IoT devices. This microphone is built with a capacitive sensing element and CMOS IC interface, enabling high-fidelity digital audio output in PDM format.
The device features an omnidirectional sensitivity pattern and offers a low total harmonic distortion, delivering a clear audio signal with a 64 dB signal-to-noise ratio and a sensitivity of -26 dBFS ±3 dB. The compact top-port HCLGA package measures only 3 mm in length and 1 mm in height, supporting surface mount assembly and EMI shielding for robust performance in electrically noisy environments.
Operating over a wide temperature range from -40 °C to +85 °C, this microphone is well-suited for use in harsh environments. It requires a single power supply voltage ranging from 1.6 V to 3.6 V, enabling low power consumption in battery-operated devices.
STMicroelectronics ensures product reliability with compliance to ECOPACK, JEDEC J-STD-020, GREEN, and RoHS standards. This model is produced in the Philippines and is not designated for automotive standard compliance.
Operates within -40°C to 85°C temperature range. Surface mount HCLGA package with EMI shielding. 64 dB signal-to-noise ratio for audio clarity. Omnidirectional polar pattern and PDM digital output. Low power consumption with 1.6 V to 3.6 V supply voltage.
4-pin interface for easy PCB integration. Manufactured using specialized silicon micromachining process. Approved under ECOPACK, JEDEC J-STD-020, GREEN and RoHS.
This microphone is ideal for industrial, consumer electronics, and IoT applications requiring compact, low-power, and high-performance audio sensing solutions. Discover more semiconductor and sensor IC solutions in our Electronics & Electricals catalog at EnvMart.
