Описание продукта:

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 I²S interface.The I²S 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)

Характеристики продукта:

1. Digital I²S interface with high precision 24-bit data

2. High signal-to-noise ratio of 61 dBA

3. High sensitivity of -26 dBFS

4. Stable frequency response from 60 Hz to 15 kHz

5. Low power consumption: low current consumption of 1.4 mA

6. High PSR: -75 dBFS

Interface Definition:

SCK : Serial data clock for I²S interface

WS : serial data word selection for I²S interface

L/R : Left/Right channel selection.

When set low, the microphone outputs the signal in the left channel of the I²S frame.

When set high, the microphone outputs the signal in the right channel

SD: Serial data output of the I²S interface.

VCC: Input power supply, 1.8V to 3.3V.

GND: Power ground
