APPLICATIONS INFORMATION
CONNECTING TO ANALOG DEVICES, INC., AUDIO
CODECS
The ADMP405 output can be connected to a dedicated codec
microphone input (see Figure 7) or to a high input impedance
gain stage (see Figure 8). A 0.1 μF ceramic capacitor placed close
to the ADMP405 supply pin is used for testing and is recom-
mended to adequately decouple the microphone from noise on
the power supply. A dc-blocking capacitor is required at the
output of the microphone.
