Product Features:
1. Digital I²S interface with high precision 24-bit data
2. High signal-to-noise ratio of 61 dBA
3. High sensitivity of -26 dBFS
4. Stable frequency response from 60 Hz to 15 kHz
5. Low power consumption: low current consumption of 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 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
SD: Serial data output of the I²S interface.
VCC: Input power supply, 1.8V to 3.3V.
GND: Power ground
