SPV61A0LR5H-1

Overview

The SPV61A0LR5H-1 is a bottom-port, omnidirectional analog MEMS microphone from Syntiant’s SiSonic series. It features a sensitivity of -40 dB ±1dB at 94dB SPL and a signal-to-noise ratio (SNR) of 66 dBA. The device operates within a voltage range of 2.3 V to 3.6 V and supports an acoustic overload point of 132 dB SPL. Its frequency response spans from 35 Hz to 18.5 kHz with a power supply rejection ratio (PSRR) of 83 dB.

Feature Summary

• Integrates high-performance SiSonic MEMS technology for superior audio fidelity
• Features a low-noise input buffer to enhance signal clarity
• Utilizes a bottom-port design suitable for compact form factors

Applications

• Voice-enabled smart home devices
• Wearable audio electronics

Procurement Notes

Verify the specific revision level against the manufacturer's latest documentation before finalizing procurement. Confirm that the analog output interface aligns with the target system's ADC requirements. Ensure the bottom-port orientation matches the mechanical enclosure design to maintain acoustic performance specifications.

Selection Notes

Select this component when a high SNR and wide dynamic range are required in a small footprint. The analog output simplifies system architecture by removing the need for digital interface logic. Consider the 2.3 V minimum operating voltage for compatibility with low-power battery-operated designs requiring efficient energy management.
