The Knowles SPH1611LR5H-1 is a miniature, high-performance, low power, bottom port silicon microphone utilizing Knowles' SiSonic MEMS technology. It comprises an acoustic sensor, a low noise input buffer, and an output amplifier, delivering excellent wideband audio performance and RF immunity.
This microphone features a matched sensitivity, high Signal-to-Noise Ratio (SNR) of 65 dB(A), and a low Total Harmonic Distortion (THD) of 0.2% typical. It operates with a supply voltage range of 1.5V to 3.6V and consumes a low supply current of 145 µA typical. The acoustic overload point is rated at 124 dB SPL typical.
Designed for demanding applications, the SPH1611LR5H-1 boasts features such as MaxRF protection and ultra-stable performance. Its omnidirectional directivity and flat frequency response make it suitable for a wide array of audio capture needs. The device is designed for standard SMD reflow soldering, facilitating integration into automated manufacturing processes.
Applications include cellphones, smartphones, laptop computers, sensors, digital still cameras, portable music recorders, and other portable electronic devices where excellent audio quality and RF immunity are critical. Its zero-height design and small package size are advantageous for space-constrained designs.
