GENERAL DESCRIPTION
This user guide applies to the following MEMS microphone
evaluation boards:
EV_INMP404-FX
EV_INMP405-FX
EV_INMP504-FX
EV_INMP510-FX
EV_ICS-40180-FX
EV_ICS-40181-FX
EV_ICS-40310-FX
EV_ICS-40212-FX
This is a simple evaluation board that allows quick evaluation
of the performance of single-ended analog MEMS
microphones. The small size and low profile of the flexible
PCB enables direct placement of the microphone into a
prototype or an existing design for an in situ evaluation. The
evaluation board consists of a bottom port microphone
soldered to a flexible PCB with color-coded wires attached.
The only other component on the board is a 0.1 μF supply
bypass capacitor.
Table 1 describes the functions of the three connection wires.
Table 2 describes the functional differences between the
different microphones that are used with this flex circuit.

EVALUATION BOARD CIRCUIT
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-40181-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.
