PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS
Figure 3. Pin Configuration (Top View, Terminal Side Down)
TABLE 6. PIN FUNCTION DESCRIPTIONS
PIN NAME TYPE FUNCTION
1
LR
Input
Left/Right channel select. When set low, the microphone outputs its signal in the left
channel of the I²S frame. When set high, the microphone outputs its signal in the right
channel.
2
CONFIG
Input
Pull to ground. The state of this pin is used at power-up.
3
VDD
Power
Power, 1.62 to 3.63 V. This pin should be decoupled to GND with a 0.1 μF capacitor.
4
GND
Ground
Ground. Connect to ground on the PCB.
5
WS
Input
Serial Data-Word Select for I²S Interface
6
SCK
Input
Serial Data Clock for I²S Interface
7
SD
Output
Serial Data Output for I²S Interface. This pin tri-states when not actively driving the
appropriate output channel. The SD trace should have a 100 kΩ pulldown resistor to
discharge the line during the time that all microphones on the bus have tri-stated their
outputs.
