It features a signal-to-noise ratio of 73 dB(A), making it a dependable option for audio capture under varying conditions. The compact size facilitates seamless integration into devices needing quality sound input without sacrificing space or performance.

• High sensitivity of -38dBV for clear audio capture
• Robust IP57 rating ensures dust and water resistance
• Omni-directional pickup pattern allows for versatile audio capture
• Integrated low noise preamplifier enhances output clarity
• Flexible power modes cater to varying energy requirements

• Well-suited for active noise cancellation systems in headphones and earbuds
• Utilised in smart speakers and home automation devices
• Appropriate for high-quality audio recording in cameras and camcorders
• Employed in industrial monitoring systems with audio detection features

The operating temperature range is -40°C to +85°C, accommodating various environments.

The omni-directional pickup pattern enables sound capture from all directions, increasing usability in multi-source audio settings.

In normal mode, current consumption ranges from 170μA to 230μA, while low power mode consumes between 70μA to 80μA, making it suitable for energy-sensitive applications.

For optimal acoustic performance, ensure that the PCB sound port is larger than the microphone's acoustic port diameter to prevent sound obstruction.
