stereo recording with 2 MEMS mics... Capturing both channels Configuration

[sakshi]

Hello everyone, 

I was trying to use 2 mics  IMP34DT05 in stereo configuration with MCU.I wanted to capture signals from both the mics as well as i want to use single mic also. Please guide how can be this configuration done in schematic and how should be the 2 mics placed together.

 

Best Regards,

Except power and GND pins, you may need to 

1. connect CLK pin3 of two mics together and connect them to MCU CLK output pin.

2. connect LR pin2 of first mic to GND while LR pin2 of second mics connected to VDD.

3. connect DOUT pin4 of two mics to two Din pins of MCU, normally MDF (Multi-function digital filter) interface.

thanks!
