The ICS43434 digital MEMS microphone module with an I2S interface that eliminates the need for A/D conversion and provides clean audio output in the range of 50 Hz to 15 kHz. With channel selection and low current consumption, it is suitable for stereo systems, voice recognition and portable applications. Compatible with popular microcontrollers, it provides high quality sound with low noise. Adafruit 6049
Description
The ICS43434 MEMS microphone module with I2S interface is a modern solution for digital audio recording, ideal for microcontrollers and single-board computers. Unlike traditional analog microphones, the ICS43434 provides a fully digital output, eliminating the need for analog-to-digital conversion. The device operates in the frequency range of 50 Hz to 15 kHz, and an integrated low-pass filter removes interference above 24 kHz. The microphone features three digital pins: Clock, Data, and Word Select, which communicate with the I2S controller in the host system. A channel select pin allows choosing between left or right, enabling the use of two modules to create a complete stereo setup. The bottom acoustic port design allows for precise orientation of the microphone toward the sound source. Low power consumption and a high signal-to-noise ratio make the module ideal for portable applications, voice recorders, voice recognition systems, and acoustic analyzers. The device is compatible with microcontrollers such as ESP32, SAMD21, RP2040, and single-board computers like the Raspberry Pi.
