Key Features of the ICS-43432
1. Unmatched Audio Quality
With a frequency range of 50Hz 20kHz, the ICS-43432 captures the full spectrum of human hearing, from deep bass to crisp highs. Its -26dB sensitivity ensures accurate sound reproduction, while the 65dB SNR (Signal-to-Noise Ratio) minimizes background interference.
2. Omnidirectional Sound Capture
The microphone s omnidirectional polar pattern picks up sound uniformly from all directions, making it perfect for conference calls, ambient recording, and multi-speaker environments.
3. Digital Output (I S Interface)
The I S digital output ensures compatibility with modern DSPs and microcontrollers, reducing analog noise and simplifying integration into digital systems.
4. Ultra-Low Power Consumption
Operating at just 1.5mA with a voltage range of 1.62V 3.63V, the ICS-43432 is ideal for battery-powered devices like wireless earbuds and smartwatches.
5. Compact & Durable Design
Measuring only 4.00mm x 3.00mm x 1.10mm, this rectangular MEMS microphone fits seamlessly into space-constrained designs. Its bottom-port configuration and solder-pad termination ensure easy PCB mounting.
