ADMP404ACEZ Microphone by Analog Devices Inc.

The ADMP404ACEZ is a high-performance, low power, omnidirectional MEMS microphone designed by Analog Devices Inc., a leader in the semiconductor industry. This compact audio sensing device is perfect for applications that require clear audio capture, such as smart devices, voice recognition systems, digital cameras, and more.

Key Features:

• Omnidirectional Response: The ADMP404ACEZ has an omnidirectional pickup pattern, which means it can capture sound with equal sensitivity from all directions. This feature makes it an ideal choice for applications where the direction of the sound source is variable or unknown.
• High Signal-to-Noise Ratio (SNR): With a high SNR of 62 dB, this microphone provides excellent sound quality by capturing more of the desired audio while suppressing background noise.
• Extended Frequency Response: The ADMP404ACEZ offers a wide frequency response range from 20 Hz to 20 kHz, ensuring accurate reproduction of the original sound across the audible spectrum.
• Low Current Consumption: Designed for battery-powered devices, the microphone operates on a low supply voltage of 1.5V to 3.3V and consumes a mere 250 µA of current, making it highly efficient for portable applications.
• Stable Performance: The device is built to deliver consistent performance over a temperature range of -40°C to +85°C, ensuring reliability in diverse environmental conditions.
• Compact and Robust: Housed in a tiny 4.72 mm × 3.76 mm × 1.00 mm surface-mount package, the ADMP404ACEZ is not only space-saving but also robust enough to withstand the rigors of modern electronic device manufacturing.

Applications:

• Smartphones and Tablets
• Bluetooth Headsets
• Conference and Huddle Room Systems
• Security and Surveillance Systems
• Home Automation and IoT Devices
