The STMicroelectronics MP45DT02TR-M is a MEMS (Micro-Electro-Mechanical System) microphone designed for audio applications. It provides a digital PDM (Pulse Density Modulation) output, enabling direct integration with digital signal processors.
This omnidirectional microphone operates within a supply voltage range of 1.64V to 3.6V, with a rated voltage of 1.8V. Its frequency response spans from 100 Hz to 10 kHz, capturing a wide range of audio frequencies. The sensitivity is specified as -26dB ±3dB at 94dB SPL, and it features a Signal-to-Noise (S/N) ratio of 61dB.
The MP45DT02TR-M consumes a low supply current of 650 µA. It is housed in a compact, rectangular package with dimensions of 4.72mm x 3.76mm and a height of 1.35mm. The termination style is solder pads, suitable for surface-mount assembly.
Environmental compliance includes RoHS3 compliance and a Moisture Sensitivity Level (MSL) of 3. The REACH status is noted as unaffected.
