TNESTAR 2pcs MS3625 Fully Compatible With INMP441 Omnidirectional Microphone Module I2S Interface High Precision for ESP32
Ciudad: EN, Sheridan
This sensor is a high-performance, low-power, digital-output omnidirectional microphone with a bottom port. It is fully compatible with INMP441.
It consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I2S interface. The I2S interface allows it to connect directly to digital processors such as DSPs and microcontrollers without the need for audio codecs in the system. Featuring a high signal-to-noise ratio, it is an excellent choice for near-field applications. With a flat broadband frequency response, it results in natural sounding high clarity.
Features:
Digital I2S interface with 24-bit accurate data
High SNR of 61 dBA
High sensitivity of -26 dBFS
Consistent frequency response from 60 Hz to 15 kHz
Low power consumption: low current draw of 1.4 mA
High PSR: -72 dBFS
Interface Definition:
SCK: Serial data clock for the I2S interface
WS: Serial data word select for the I2S interface
L/R: Left/Right channel selection:
When set to low, the microphone outputs its signal on the left channel of the I2S frame.
When set to high, the microphone outputs its signal on the right channel.
SD: Serial data output for the I2S interface
VCC: Input power supply, ranging from 1.6V to 3.6V
GND: Power ground
Connection to ESP32 Development Board:
Module -- ESP32 Development Board
SCK -- GPIO14
SD -- GPIO32
WS -- GPIO15
L/R -- GND
GND -- GND
VDD -- VDD3.3
