EVAL-ADMP411Z-FLEX: Bottom-Ported Analog Output MEMS Microphone

Evaluation Board

GENERAL DESCRIPTION

EVALUATION BOARD CIRCUIT

The EVAL-ADMP411Z-FLEX is a simple evaluation board that

Figure 1 shows the schematic of the EVAL-ADMP411Z-FLEX,

and Figure 2 shows the layout of the EVAL-ADMP411Z-FLEX.

See the ADMP411 data sheet for a complete description and

specifications of the microphone.

allows quick evaluation of the performance of the ADMP411

MEMS microphone. 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

EVAL-ADMP411Z-FLEX consists of an ADMP411 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.
