7SDOutput

Serial Data Output for I²S Interface. This pin tristates when not actively driving the appropriate
output channel. The SD trace should have a 100 kΩ pull‐down resistor to discharge the line
during the time that all microphones on the bus have tristated their outputs.

8VDD

Power

1.8 to 3.3 V. This pin should be decoupled to Pin 1 with a 0.1 μF capacitor and a 10μF capacitor.

RECOMMENDED INTERFACE CIRCUIT：

Stereo Output I2S Format

Mono Output I2S Format Left Channel ( L/R = 0)

Mono Output I2SFormat Right Channel ( L /R = 1)

I²S DATA INTERFACE
The serial data is in slave mode I²S format, which has 24‐bit depth in a 32 bit word. In a
stereo frame there are 64 SCK cycles, or 32 SCK cycles per data‐word. When L/R=0, the output
data in the left channel, while L/R=Vdd, data in the right channel. The output data pin (SD) is
tri‐stated after the LSB is output so that another microphone can drive the common data line.
Data Word Length
The output data‐word length is 24 bits per channel. The Mic must always have 64 clock
cycles for every stereo data‐word (fSCK = 64 × fWS).
Data‐Word Format
The default data format is I²S, MSB‐first. In this format, the MSB of each word is delayed by© 2011‐2017 MEMSensing Microsystems (Suzhou,China) Co. Ltd, — Ver.1.1. DOC NO:DS‐050. All rights reserved
