ADMP522ACEZ-RL7 Ultra-Low Noise Microphone with Bottom Port and Analog Output

The ADMP522ACEZ-RL7 is a high-performance, ultra-low noise, low power, analog output, bottom-ported omnidirectional MEMS microphone from Analog Devices Inc. This state-of-the-art microphone is designed for professional-grade audio recording in a wide range of applications, from consumer electronics to industrial and automotive systems. The device offers unparalleled sound quality with its high signal-to-noise ratio (SNR) and extended frequency response, making it an ideal choice for applications requiring clear and precise audio capture.

The microphone features a sensitivity of -38 dBV/Pa and an acoustic overload point of 120 dB SPL, providing a wide dynamic range for capturing both soft and loud sounds with clarity. Its ultra-low noise floor of 29 dBA SPL ensures that even the most subtle sounds are recorded without unwanted background noise. With a flat wideband frequency response from 100 Hz to 15 kHz, the ADMP522ACEZ-RL7 captures the full audible spectrum with accuracy, preserving the integrity of the original sound.

Engineered for ease of integration into a variety of designs, the microphone's compact package measures just 3.35 mm x 2.50 mm x 0.98 mm. It is reflow-solder-compatible with no sensitivity degradation, which simplifies the manufacturing process and ensures robust performance after assembly. The ADMP522ACEZ-RL7 also features a high PSR (Power Supply Rejection) of 70 dB, minimizing the impact of power supply noise on audio quality.

With a low current consumption of only 250 µA, the ADMP522ACEZ-RL7 is optimized for battery-powered devices, where power efficiency is critical. Its wide operating temperature range from -40°C to +85°C ensures reliable operation in diverse environmental conditions.

The ADMP522ACEZ-RL7 is supplied on tape and reel, making it suitable for high-volume production. Its quality and performance are backed by Analog Devices Inc., a leader in high-performance analog technology. Whether for smartphones, tablets, smart home devices, or high-end audio equipment, the ADMP522ACEZ-RL7 offers a perfect blend of audio performance, power efficiency, and ease of integration for the most demanding audio applications.
