Integrated lowpass filter: an integrated lowpass filter suppresses frequency noise, improving audio purity during transmission. Wide range of applications: suitable for intelligent home, robotics, and voice recognition systems, as well as other applications, providing a flexible audio capture solution. Simple and fast integration: uses the I2S interface for easy connection directly with a variety of microcontrollers, greatly reducing development effort. Costeffective auditory solution: the ICS43434 I2S MEMS microphone module delivers clear recordings with a signaltonoise ratio (SNR) of 65 dB. Use scenarios Smart home devices: voice assistants, wakeword detection, and voicecontrolled sensors in smart speakers and connected home appliances. Robotics: humanrobot interaction and onboard voice control for autonomous or semiautonomous robots. Embedded voice recognition: ondevice speech capture for IoT devices and consumer electronics requiring reliable audio input for recognition systems.
