Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1xOmnidirectional Microphone Module Thin Surface-Mount Package with RoHS Compatibility: The INMP441 omnidirectional microphone module is packaged in a thin 4.72 x 3.76 x 1 mm surface-mount package. It is compatible with reflow soldering and maintains sensitivity without degradation. Additionally, the INMP441 is halogen-free, adhering to environmental standards. Clear and Natural Sound with High SNR: The INMP441 digital output sensor module features a flat wideband frequency response, resulting in natural sound reproduction with high clarity. Its high signal-to-noise ratio (SNR) makes it a perfect choice for near-field applications. Direct Connection to Digital Processors: Thanks to the I²S interface, the INMP441 can be directly connected to digital processors such as DSPs and microcontrollers without the need for audio codecs in the system. Complete INMP441 Solution with Industry-Standard 24-bit I²S Interface: The INMP441 solution includes a MEMS sensor, signal conditioning, analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I²S interface. High-Performance, Low-Power Digital MEMS Microphone: The INMP441 digital output sensor module is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port.
