GENERAL DESCRIPTION

The EVAL-ADMP441Z-FLEX is a simple evaluation board that

allows quick evaluation of the performance of the

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-ADMP441Z-FLEX consists of an

soldered to a flexible PCB. The only other component on the

board is a 0.1 μF supply bypass capacitor.

The flex PCB is designed to mate to a ZIF connector with

1.0 mm pin spacing. The Molex 52610-1071 connector is

included in the kit with the flex PCB. The flex PCB can be

mated to the connector by first pulling out the connector’s

tan clamp, inserting the flex PCB, and then pushing the clamp

closed. Wires can be soldered directly to this connector’s pins

or it can be mounted directly on a rigid PCB for evaluation. It is

recommended to use 28 AWG or smaller wire for soldering to

this connector’s pins. The PCB thickness at the pin edge is 0.3 mm.
