| SPA2410LR5H-B Low Noise Zero-Height SiSonicTM Microphone The SPA2410LR5H-B is a miniature, highperformance, low power, bottom port silicon microphone. Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPA2410LR5H-B 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 x Low Noise x Flat Frequency Response x Small package x Low Current x MaxRF protection x Zero-Height MicTM x Ultra-Stable Performance x Standard SMD Reflow x Omnidirectional 5/20/2013 Knowles Electronics SPA2410LR5H-B ABSOLUTE MAXIMUM RATINGS Parameter VDD to Ground OUT to Ground Input Current to Any Pin Temperature Range Absolute Maximum Rating VDD + ±5 -40 to +100 Units V mA °C Stresses exceeding these “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only. Functional operation at these or any other conditions beyond those indicated under “Acoustic & Electrical Specifications” is not implied. Exposure beyond those indicated under “Acoustic & Electrical Specifications” for extended periods may affect device reliability.
