SPU0410LR5H-QB

Overview

The Syntiant SPU0410LR5H-QB is an omnidirectional analog MEMS microphone with a frequency range of 100 Hz to 80 kHz. It operates on a voltage supply between 1.5 V and 3.6 V, drawing 160 µA of current. The device features a sensitivity of -38dB ±3dB @ 94dB SPL and an impedance of 400 Ohms. Packaged in a rectangular surface-mount form factor measuring 3.76mm x 2.24mm x 1.20mm, it utilizes solder pads for termination.

Feature Summary

• Bottom-port acoustic design enabling ultrasonic response up to 80 kHz
• Low-power analog silicon construction suitable for battery-operated devices
• Omnidirectional pickup pattern for uniform sound capture

Applications

• Ultrasonic sensing and detection systems
• Voice recognition modules requiring extended frequency response
• Consumer electronics audio input interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeits. Confirm RoHS compliance status matches current manufacturing standards. Check for specific suffix variations that may indicate different packaging or testing grades. Ensure compatibility with existing PCB footprint dimensions before finalizing procurement orders.

Selection Notes

Select this model when applications require analog output combined with ultrasonic capability beyond standard audio ranges. Compare sensitivity specifications against ambient noise requirements. Evaluate power consumption constraints relative to the 160 µA operating current. Ensure system voltage rails align with the 1.5 V to 3.6 V operational window for stable performance.

Part Context

This component belongs to the SiSonic™ family of MEMS microphones manufactured by Syntiant. These devices integrate silicon-based acoustic sensors designed for compact electronic assemblies. The series emphasizes low power consumption and small form factors for modern portable and IoT applications.

Replacement Considerations

SPQ1410HR5H-B is a related Syntiant MEMS microphone offering similar analog functionality but with a narrower frequency range limited to 10 kHz. Verify if the extended ultrasonic bandwidth of the SPU0410LR5H-QB is critical for the target application before substituting.
