It is reflow- solder compatible with no sensitivity degradation. The INMP441 is halide free.\u003cbr\u003e\nThe INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a flat wideband frequency response that results in high definition of natural sound.\u003cbr\u003e\nSCK: Serial data clock for I2S interface; WS: Serial data word selection for I2S interface; L\/R: Left\/Right channel selection.\u003cbr\u003e\nApplications: Teleconferencing Systems; Remote Controls ; Gaming Consoles; Mobile Devices ;Laptops Tablets ;Security Systems\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eProduct Features:\u003c\/strong\u003e\u003cbr\u003e\n1.
