About this item The INMP441 is a high performance, low-power omnidirectional MEMS microphone with a base port. The complete INMP441 solution includes MEMS sensor, signal conditioning, analog-to-digital converter, anti-aliasing filters, power management and an industry-standard 24-bit I²S interface. The I²S interface allows the INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system. The INMP441 has a high RSB, making it an excellent choice for near-field applications. The INMP441 has a flat broadband frequency response, which allows to achieve natural sound with high intelligibility. The INMP441 is available in a 4.7 x 3.75 x 1.0 mm thin surface mount box. It is compatible with reflow soldering without degradation of sensitivity. INMP441 is halide free.
