INMP441 Omnidirectional Microphone Module

INMP441 MEMS High Precision Omnidirectional Microphone Module has a high signal-to-noise ratio, suitable for near-field applications. It has an I2S interface that allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system.

Features:

• It has a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port.
• It has a digital I2S interface with high-precision 24-bit data.
• Low power consumption, low current consumption
• It has a high PSR: -75 dBFS
• Interface definition:
• SCK: Serial data clock of I2S interface
• WS: Serial data word selection for I2S interface
• L/R: left/right channel selection.
• When set to a low level, the microphone outputs signals on the left channel of the I2S frame.
• When set to the high level, the microphone outputs the signal on the right channel
• SD: Serial data output of I2S interface.
• VCC: Input power, 1.8V to 3.3V.
• GND: power ground

Package Includes:

1 x INMP441 MEMS High Precision Omnidirectional Microphone Module I2S Interface Supports ESP32
