MS3625 Omnidirectional Microphone Module I2S Interface MEMS High-Precision Compatible with INMP441 Not Welding leírása

This sensor is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. Compatible with INMP441.
Consists of a MEMS sensor, signal composition modulation, analog-to-digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface.
The I2S interface allows it to connect directly to digital processors such as DSPS and microcontrollers without the use of audio codecs used in the system. With a high signal-to-noise ratio, it is an excellent choice for near-field applications. With flat broadband frequency response, resulting in natural sound with high definition.

Main features:
Digital I2S interface with high precision 24-bit data
High SNR of 61 dBA
High sensitivity -26 dBFS
Stable frequency response from 60 Hz to 15 kHz
Low power consumption: Low current consumption of 1.4 mA
High PSR: -72 dBFS
Interface definition:
SCK: Serial data clock for the I2S interface
WS: Serial data word selection for the I2S interface
L/R: Left/right channel selection:
Set to low power level, the microphone outputs a signal in the left channel of the I2S frame.
Set to high power level, the microphone outputs a signal in the right channel.
: Serial data output for the I2S interface
VCC: Input power, 1.6V to 3.6V
GND: Power source
