Figure 1 shows the schematic of the evaluation board, and Figure 2 shows the flex board layout. See the respective microphone data sheets for complete descriptions and specifications of the microphones. Note that the layout for the EV_ICS-40180-FX differs slightly from what is shown in Figure 2 because of this part’s different package footprint, but the routing of the three signals is consistent.
