Description

Applications: Teleconferencing systems, remote controls, game consoles, mobile devices, laptops, tablets, security systems. The I2S interface allows the INMP441 to be connected directly to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system. 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, analogue 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. › See more product details; Product description Features: 1.
