AITRIP 5PCS INMP441 Omnidirektionales Mikrofonmodul I2S-Schnittstelle MEMS Hochpräzise Low Power Kompatibel mit ESP32

Produktbeschreibung

Anwendungen: Telekonferenzsysteme, Fernbedienungen, Spielkonsolen, Mobilgeräte, Laptops, Tablets, Sicherheitssysteme. Die I2S-Schnittstelle ermöglicht den direkten Anschluss des INMP441 an digitale Prozessoren wie DSPs und Mikrocontroller, ohne dass ein Audio-Codec für die Verwendung im System erforderlich ist. The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. Digital I2S interface with high precision 24-bit data; High signal to noise ratio is 61 dBA; High sensitivity - 26 dBFS; Stable frequency response from 60 Hz to 15 kHz; Low power consumption: low current consumption 1.4 mA;High PSR: -75 dBFS The 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.
