Produktbeschreibung:<\/h4>\n
The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS transducer, signal composition conditioning, analog-to-digital converter, anti-alias filter, power management, and industry-standard 24-bit I\u00b2S interface.The I\u00b2S interface allows the INMP441 to connect directly to digital processors such as DSPs and microcontrollers without the need to use audio codecs for use with the system.The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. The INMP441 has a flat broadband frequency response resulting in natural sounding high definition.Translated with www.DeepL.com\/Translator (free version)<\/div>\n

Interface Definition:<\/h4>\n

SCK : Serial data clock for I\u00b2S interface<\/p>\n

WS : serial data word selection for I\u00b2S interface<\/p>\n

L\/R : Left\/Right channel selection.<\/p>\n

When set low, the microphone outputs the signal in the left channel of the I\u00b2S frame.<\/p>\n

When set high, the microphone outputs the signal in the right channel<\/p>\n

SD: Serial data output of the I\u00b2S interface.<\/p>\n

VCC: Input power supply, 1.8V to 3.3V.<\/p>\n

GND: Power ground<\/p>\n
