SPV08A0LR5H-1

Overview

The SPV08A0LR5H-1 is a miniature, high-performance, low-power analog bottom port silicon microphone from the SiSonic series. It features an omnidirectional acoustic response with a sensitivity of -42 dBV/Pa and a signal-to-noise ratio of 64.5 dB. The device operates on a supply voltage range of 2.3 V to 3.6 V with a typical current consumption of 180 µA. Its frequency range spans 20 Hz to 10 kHz, and it utilizes a differential mode configuration to enhance noise immunity against power supply variations.

Feature Summary

• Bottom port silicon MEMS construction for compact integration
• Differential output configuration to improve power supply noise immunity
• Low power operation suitable for battery-powered devices

Applications

• Voice-enabled consumer electronics
• Smart home audio devices
• Portable communication equipment

Procurement Notes

This component is officially obsolete and no longer manufactured by Syntiant. Verification of availability should focus on distributor surplus stock or authorized secondary market channels rather than direct manufacturer orders. Confirm RoHS compliance status through specific lot documentation as standard production records are archived.

Selection Notes

Engineers replacing this part must account for its discontinued status. Selection criteria should prioritize matching the -42 dBV/Pa sensitivity and 64.5 dB SNR specifications. Ensure substitute components support the same 2.3 V to 3.6 V operating voltage and bottom port acoustic interface to maintain PCB layout compatibility.

Part Context

Part of the SiSonic family of analog MEMS microphones designed for voice applications. It shares architectural similarities with other bottom port models in the series but is distinguished by its specific sensitivity and noise performance metrics tailored for general voice capture tasks.

Replacement Considerations

Public confirmed substitutes include CMM-2718AB-38108-TR from Same Sky (formerly CUI Devices). Verify electrical parameter alignment before adoption.
