Overview
The Syntiant SPUL409HE5H is a silicon MEMS microphone featuring analog output and omnidirectional sensitivity. It operates within a voltage range of 1.5 V to 3.6 V with a supply current of 190 µA. The device exhibits a frequency response from 100 Hz to 10 kHz and a sensitivity of -42 dB ±3 dB at 94 dB SPL. Key electrical parameters include a signal-to-noise ratio of 59 dB and an impedance of 300 Ohms. The component utilizes a top port configuration and solder pad termination, housed in a rectangular package measuring 3.76 mm x 2.95 mm.
Feature Summary
- Analog output interface for direct signal processing
- Omnidirectional acoustic pickup pattern
- Low power consumption design suitable for battery-operated devices
Applications
- Voice recognition systems
- Smart home audio interfaces
- Portable consumer electronics
Procurement Notes
Verify the specific suffix (e.g., PB-2) against the required packaging format, as standard distribution often uses tape and reel configurations. Confirm end-of-life status with the manufacturer or authorized distributors, as this component may be discontinued. Ensure compatibility with existing PCB footprints and acoustic venting requirements during integration planning.
Selection Notes
Select this model when analog output is preferred over digital PDM interfaces to reduce system complexity. Consider the 190 µA supply current for strict power budget constraints. Evaluate the 59 dB SNR and -42 dB sensitivity against ambient noise requirements. Verify that the 300 Ohm impedance matches the input stage of the connected amplifier or ADC.
Part Context
This component belongs to the SiSonic™ series of MEMS microphones manufactured by Syntiant. The series focuses on low-power audio sensing solutions. The SPUL409HE5H variant specifically targets applications requiring analog signal output with high sensitivity and wide bandwidth characteristics compared to lower-frequency variants.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Syntiant replacement guides or contact technical support for qualified alternatives.
