What is the operating temperature range for this MEMS microphone?

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

How does the microphone’s design assist in sound capture?

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

What current consumption levels can be expected in different power modes?

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.

Are there specific mounting requirements for optimal performance?

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

What calibration method is used for the microphone?

Each microphone undergoes calibration with an advanced Infineon calibration algorithm, resulting in small sensitivity tolerances of ±1dB.
