Description
5 INMP441 omnidirectional microphone modules, MEMS high-precision low-power I2S interface - A1
Product Description
Product Introduction:
The INMP441 is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom-mounted interface.
A complete 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. The I2S interface allows the INMP441 to connect directly to digital processors such as DSPs and microcontrollers, enabling system use without an audio codec.
The INMP441 features a high signal-to-noise ratio, making it ideal for near-field applications. The INMP441 has a flat, wideband frequency response for high-definition, natural sound. Product Features: 1. High-precision 24-bit digital I2S interface 2. High signal-to-noise ratio: 61 3. High sensitivity: -26 dBFS 4. Stable frequency response: 60Hz to 15kHz 5. Low power consumption: 1.4 mA 6. High PSR: -75 dBFS Interface Definitions: 1. : Serial data clock for the I2S interface 5. WS: Serial data word for the I2S interface 6. L / R: Left channel / Right channel. When set low, the microphone outputs the signal in the left channel of the I2S frame. When set high, the microphone outputs the signal in the right channel. 7. SD: Serial data output for the I2S interface. VCC: Input power supply, 1.8V to 3.3V. GND: Ground.
