This sensor is a high-performance, low-power, digital-output omnidirectional

microphone with a bottom port. It is fully compatible with INMP441.

It consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I2S interface. The I2S interface allows it to connect directly to digital processors such as DSPs and microcontrollers without the need for audio codecs in the system. Featuring a high signal-to-noise ratio, it is an excellent choice for near-field applications. With a flat broadband frequency response, it results in natural sounding high clarity.

Features:

Digital I2S interface with 24-bit accurate data

High SNR of 61 dBA

High sensitivity of -26 dBFS

Consistent frequency response from 60 Hz to 15 kHz

Low power consumption: low current draw of 1.4 mA

High PSR: -72 dBFS

Interface Definition:

SCK: Serial data clock for the I2S interface

WS: Serial data word select for the I2S interface

L/R: Left/Right channel selection:

When set to low, the microphone outputs its signal on the left channel of the I2S frame.

When set to high, the microphone outputs its signal on the right channel.

SD: Serial data output for the I2S interface

VCC: Input power supply, ranging from 1.6V to 3.6V

GND: Power ground
