MP34DT05JTR

Microphones Overview

The MP34DT05JTR is an ultra-compact, low-power, omnidirectional digital MEMS microphone manufactured by STMicroelectronics. It integrates a capacitive sensing element with a CMOS IC interface to provide a PDM digital output. The device features a sensitivity of –26 dBFS ±3 dB and a signal-to-noise ratio of 64 dB. It operates on a single supply voltage ranging from 1.6 V to 3.6 V. The component is housed in a top-port, SMD-compliant, EMI-shielded HCLGA package with dimensions of 3mm x 1mm x 1mm. It is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

Microphones Procurement Notes

Verify the specific suffix (e.g., JTR vs TR-A) against official datasheets to confirm pinout and packaging details. Ensure compatibility with PDM interfaces on target processors. Confirm environmental compliance requirements such as RoHS status before integration into final assemblies.

Microphones Selection Notes

Select this component for designs requiring a compact, low-power digital microphone solution. Consider the 64 dB SNR and -26 dBFS sensitivity for standard voice capture needs. Verify that the system power supply falls within the 1.6 V to 3.6 V operating range and that the PCB layout supports the HCLGA-4 package footprint.

Microphones Part Context

This part belongs to the MP34DTx series of MEMS audio microphones from STMicroelectronics. These sensors utilize specialized silicon micromachining for the sensing element and CMOS processes for the interface circuitry. The series is designed for high-volume consumer electronics where size, power consumption, and acoustic performance are critical constraints.

Microphones Replacement Considerations

The MP34DT05 is listed as obsolete. Check for availability of the MP34DT05-A or MP34DT05TR-A variants. Verify mechanical footprint and electrical parameters when substituting with other models in the MP34DTx family.
