Package included: 10pcs INMP441 Omnidirectional Microphone Module MEMS High-Precision Low Power 24 Bit Data I2S Interface Digital Output High Sensitivity I2S Interface Supports ESP32

• 【Description】The INMP441 is a high performance, low power, digital output, omnidirectional EMS microphone with a bottom port. The complete INMP441 solution consists of a MEMS sensor, signal composition conditioning, analog-to-digital converter, anti-aliasing filter, power management and industry standard 24-bit I²S interface.
• 【Feature】The I²S interface allows the INMP441 to connect directly to digital processors such as DSPS and microcontrollers without the use of the audio codecs used in the system. With a high signal-to-noise ratio, the INMP441 is an excellent choice for near-field applications. The INMP441 has a flat broadband frequency response, resulting in natural sound with high definition.
• 【Specification】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 1.4mA. High PSR: -75 dBFS.
• 【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. SD: Serial data output for the I²S interface. VCC: Input power, 1.8V to 3.3V. GND: Power Source Ground.
