Brand: Teyleten Robot
Features:
- INMP441 is a high performance, low power consumption, digital output, omnidirectional MEMS microphone with bottom port
- The complete INMP441 solution consists of a MEMS sensor, signal composition conditioning, analog-to-digital converter, anti-aliasing filter, power management and industry standard 24-bit I²S interface.
- The I²S interface allows INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for the audio codec used in the system
- INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat broadband frequency response, resulting in high definition of natural sound.
