Product Features:
1. Digital I²S interface with high precision 24-bit data
2. High signal to noise ratio is 61 dBA
3. High sensitivity - 26 dBFS
4. Stable frequency response from 60 Hz to 15 kHz
5. Low power consumption: low current consumption 1.4 mA
6. High PSR: -75 dBFS
Interface definition:
SCK: Serial data clock for I2S interface
WS: Serial data word selection for I2S interface
L/R: Left/Right channel selection.
When set to low, the microphone outputs a signal on the left channel of the I2S frame.
When set to high level, the microphone outputs signals on the right channel
SD: Serial data output of the I²S interface.
VCC: Input power, 1.8V to 3.3V.
GND: power ground
