The SPV0142LR5H-1 is a miniature, high-performance, low power,
matched sensitivity bottom port silicon microphone. Using Knowles’
proven high performance SiSonic™ MEMS technology, the
SPV0142LR5H-1 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
