SPU0410LR5H-PB

Overview

The SPU0410LR5H-PB is a legacy bottom port analog MEMS microphone manufactured by Syntiant. It operates within a voltage range of 1.5 V to 3.6 V and draws a supply current of 160 µA. The device features an omnidirectional acoustic response with a sensitivity of -38 dB ±3 dB at 94 dB SPL. Its frequency range extends from 100 Hz to 80 kHz, providing a signal-to-noise ratio of 63 dB. The component utilizes solder pad termination and is housed in a miniature package suitable for portable electronics.

Feature Summary

• Bottom port design facilitates easy integration into compact devices
• Low power consumption suitable for battery-operated applications
• Omnidirectional acoustic pickup pattern ensures consistent audio capture

Applications

• Portable electronic devices
• Audio sensor modules
• Voice recognition systems

Procurement Notes

Verify the specific suffix 'PB' against official manufacturer documentation to confirm exact mechanical dimensions and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier or manufacturer datasheet prior to procurement. Ensure compatibility with existing PCB footprints as legacy components may have specific handling requirements.

Selection Notes

Select this component when a low-power analog output is required for voice processing applications. The bottom port configuration is advantageous for space-constrained designs where top-port access is obstructed. Verify that the 63 dB SNR meets system noise floor requirements. Consider the 160 µA operating current for strict power budget constraints in always-on listening devices.
