DMM-4326-T-R

Microphones Overview

The PUI Audio DMM-4326-T-R is a digital MEMS microphone featuring a silicon diaphragm and omnidirectional acoustic port. It operates on a supply voltage range of 1.5 V to 3.6 V with a typical sensitivity of -26 dB ±1 dB. The device delivers a frequency response spanning 20 Hz to 18 kHz and utilizes Pulse Density Modulation (PDM) for digital audio output. Physical dimensions are 4.00 mm x 3.00 mm x 1.00 mm, housed in a compact surface-mount package suitable for automated assembly.

Microphones Procurement Notes

Verify the specific suffix 'T-R' corresponds to the tape-and-reel packaging configuration required for your manufacturing line. Confirm that the 1.5 V to 3.6 V operating voltage aligns with your system's power rail. Ensure the PDM output protocol matches your host processor or codec capabilities before finalizing procurement.

Microphones Selection Notes

Select this component when a low-profile, digitally integrated microphone is required for space-constrained designs. The wide supply voltage range offers flexibility in power management strategies. The standard PDM interface simplifies integration with common digital signal processors without requiring external analog-to-digital conversion stages.

Microphones Part Context

This part belongs to the DMM series of digital MEMS microphones from PUI Audio. The series focuses on providing high-fidelity audio capture in miniature form factors. The DMM-4326-T-R specifically targets applications demanding reliable voice input with minimal board space utilization.

Microphones Replacement Considerations

Direct substitutes within the same DMM series include DMM-4026-B-R and DMM-4326-2-T. Verify pin compatibility and electrical specifications such as sensitivity and SNR when cross-referencing these alternatives.
