Analog Devices ADMP441 MEMS Microphone Datasheet
The ADMP441 is an omnidirectional MEMS microphone featuring a bottom port for noise rejection. It includes a complete solution with the MEMS sensor, signal conditioning, ADC, anti-aliasing filter, power management, and a standard 24-bit I2S interface, eliminating the need for external audio codecs in many applications.
Key specifications include a high signal-to-noise ratio of 61 dBA, sensitivity of -26 dBFS at 94 dB SPL, and a flat frequency response from 60 Hz to 15 kHz. The device operates on a supply voltage between 1.8 V and 3.3 V with low power consumption in normal mode (1.4 mA). It is housed in a compact 4.72 mm x 3.76 mm x 1 mm surface-mount package compatible with lead-free soldering. This manual is written in Chinese.
