ICS-43434 I2S MEMS Microphone Module

Product Characteristics:
High-precision 24-bit data digital I2S interface
High signal-to-noise ratio of 61 dBA
High sensitivity -26 dBFS
Stable frequency response from 60Hz to 15kHz
Low power consumption: Low current consumption 1.4 mA
High PSR: -75 dBFS
Module size: 14mm * 14mm/0.55inch * 0.55inch (D * D)

Interface Definition:
SCK: Serial data clock of I2S interface
WS: Serial Data Word Selection for I2S Interface
L/R: Left/Right channel selection
Set to low battery level, the microphone outputs signal on the left channel of the I2S frame
Set to a high level, the microphone outputs a signal on the right channel The serial data output of SD: I2S interface
