Overview
SPU1410LR5H-QB Zero-Height SiSonicTM Microphone With Extended Low Frequency Performance The SPU1410LR5H-QB is a miniature, highperformance, low power, bottom port silicon microphone.
Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPU1410LR5H-QB consists of an acoustic sensor, a low noise input buffer, and an output amplifier.
These devices are suitable for applications such as cellphones, smart phones, laptop computers, sensors, digital still cameras, portable music recorders, and other portable electronic devices where excellent wideband audio performance and RF immunity are required.
Features:  Extended Low Frequency Performance  Flat Frequency Response  Low Current  Small package  MaxRF protection  Zero-Height MicTM  Ultra-Stable Performance  Standard SMD Reflow  Omnidirectional Revision: D Sheet 1 of 11 3/27/2013 ©2013 Knowles Electronics SPU1410LR5H-QB 1.
