Figure 2-1. Typical Connection Diagram

Stereo connection of two CS7250B digital microphones is shown in Fig. 2-1.

It is recommended to connect a 0.1-

F decoupling capacitor between the VDD and GND pins of the CS7250B. A ceramic

0.1-

F capacitor with X7R dielectric or better is suitable. The capacitor should be placed as close to the CS7250B as

possible.
