Revision: B 2/17/2013 Sheet 1 of 11 ©2014 Knowles Electronics SPV1840LR5H-B Zero-Height SiSonicTM Microphone The SPV1840LR5H-B is a miniature, high- performance, low power, bottom port silicon microphone. Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPV1840LR5H-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: Small package Flat Frequency Response Low Current MaxRF protection Zero-Height MicTM Ultra-Stable Performance Standard SMD Reflow Omnidirectional

ABSOLUTE MAXIMUM RATINGS Parameter Absolute Maximum Rating Units VDD to Ground -0.5, +5.0 V OUT to Ground -0.3, VDD + 0.3 V Input Current to Any Pin ±5 mA Temperature Range -40 to +100 °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. 2.
