SPM0404HE5H

Overview

The Syntiant SPM0404HE5H is a mini surface-mount silicon MEMS microphone featuring an analog output and omnidirectional acoustic porting. It operates within a voltage range of 1.5 V to 3.6 V, drawing a supply current of 190 µA. The device provides a sensitivity of -42 dB ±3 dB at 94 dB SPL and achieves a signal-to-noise ratio (SNR) of 59 dB. Its frequency response spans from 100 Hz to 10 kHz with an impedance of 300 Ohms. The component measures 3.76 mm in length, 2.95 mm in width, and has a maximum height of 1.20 mm.

Feature Summary

Integrated enhanced RF protection for improved signal integrity in noisy environments
Omnidirectional acoustic design suitable for diverse voice capture applications
Low-power analog operation optimized for battery-constrained portable devices

Applications

Voice-controlled consumer electronics
Portable audio recording devices
Hands-free communication modules

Procurement Notes

Verify the specific suffix (e.g., -PB) against official datasheets to confirm package type and termination style. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Check for obsolescence notices as this component family may have limited availability or replacement options.

Selection Notes

Select this model for applications requiring low power consumption and high RF immunity. Ensure the host circuit supports analog microphone interfaces rather than PDM digital outputs. Verify that the mechanical footprint accommodates the specified dimensions and that the operating voltage aligns with the system's power rails.

Part Context

This component belongs to the SiSonic™ series of MEMS microphones manufactured by Syntiant. The series focuses on providing high-performance acoustic sensing solutions with integrated protection features. These microphones are designed to replace traditional electret condenser microscopes in modern compact electronic designs.
