SPV1840LR5H

Overview

The SPV1840LR5H is an omnidirectional analog MEMS microphone manufactured by Syntiant. It operates within a voltage range of 1.5 V to 3.6 V and features a frequency response spanning from 100 Hz to 10 kHz. The device provides a sensitivity of -38dB ±3dB at 94dB SPL. Designed for low-power applications, it utilizes solder pad termination and is available in a rectangular package suitable for surface-mount assembly.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Analog output signal interface
• Low power consumption operation

Applications

• Voice recognition systems
• Smart home audio devices
• Portable consumer electronics

Procurement Notes

Verify the specific suffix variant (e.g., -B) required for your application, as packaging and minor specifications may differ between versions. Confirm RoHS compliance status with the manufacturer or authorized distributor before finalizing procurement orders to ensure regulatory adherence.

Selection Notes

Select this component when a compact, low-power analog microphone is needed for voice-centric applications. Ensure the host system supports the 1.5 V to 3.6 V supply range and can interface directly with the analog output without requiring digital conversion hardware initially.

Part Context

This part belongs to Syntiant's SiSonic™ MEMS microphone family, which focuses on high-performance audio sensing for AI-enabled devices. The SPV1840 series offers a balance of size, power efficiency, and acoustic performance for embedded audio processing tasks.

Replacement Considerations

Check for direct substitutes like the SPV1840LR5H-B if the standard version is unavailable. Verify pin compatibility and sensitivity tolerances before swapping with other MEMS microphones from different manufacturers.
